IPython 0.7.3 is out
Hi all, The IPython team is happy to release version 0.7.3, with a lot of new enhancements, as well as many bug fixes (including full Python 2.5 support). We hope you all enjoy it, and please report any problems as usual. WHAT is IPython? 1. An interactive shell superior to Python's default. IPython has many features for object introspection, system shell access, and its own special command system for adding functionality when working interactively. 2. An embeddable, ready to use interpreter for your own programs. IPython can be started with a single call from inside another program, providing access to the current namespace. 3. A flexible framework which can be used as the base environment for other systems with Python as the underlying language. 4. A shell for interactive usage of threaded graphical toolkits. IPython has support for interactive, non-blocking control of GTK, Qt and WX applications via special threading flags. The normal Python shell can only do this for Tkinter applications. Where to get it --- IPython's homepage is at: http://ipython.scipy.org and downloads are at: http://ipython.scipy.org/dist We've provided: - Source download (.tar.gz) - A Python Egg (http://peak.telecommunity.com/DevCenter/PythonEggs). - A native win32 installer. We note that IPython is now officially part of most major Linux and BSD distributions, so packages for this version should be coming soon, as the respective maintainers have the time to follow their packaging procedures. Many thanks to Jack Moffit, Norbert Tretkowski, Andrea Riciputi, Dryice Liu and Will Maier for the packaging work, which helps users get IPython more conveniently. Many thanks to Enthought for their continued hosting support for IPython. Release notes - See http://projects.scipy.org/ipython/ipython/wiki/Release/0.7.3/Features for notable new features in this release. Enjoy, and as usual please report any problems.

itools 0.15.0 released
itools is a Python library, it groups a number of packages into a single
meta-package for easier development and deployment:
itools.catalogitools.http itools.uri
itools.cmsitools.i18n itools.vfs
itools.csvitools.ical itools.web
itools.datatypes itools.rss itools.workflow
itools.gettextitools.schemas itools.xhtml
itools.handlers itools.stl itools.xliff
itools.html itools.tmx itools.xml
The template language STL has seen the most important change since its
inception. A new method for variable substitution has been implemented,
it replaces stl:attributes and stl:content. To illustrate this change,
while before we wrote:
a stl:attributes=href object_uri stl:content=object_title /
Now we will write:
a href=${object_uri}${object_title}/a
This new approach produces more compact and readable templates. It will
also make easier to build some user interfaces. And will help translators
since the messages extracted from the templates will be more easy to read.
This release is also the first to include some C code. We have rewritten
the XML parser (itools.xml.parser) in C for performance. The programming
interface is mostly the same (see the UGRADE.txt file for the incompatible
changes).
For those who wonder... Why yet-another-xml-parser? Because its programming
interface is much much simpler (that means better) than the parsers based
in back-calls. See the itools documentation to know more [1].
The other big changes in this release are in itools.cms, one is for
disk usage, the other is functional.
The code that implements transactions has been rewritten. From a brute
force technique we have moved to a refined one that takes advantage of
the extensibility of the itools.vfs layer. The visibile change is that
we don't need anymore a backup database, so the size of an instance has
been reduced to (almost) the half.
The functional change has to do with user management. Now we use the
email address to identify users, instead of a username. The user must
confirm the registration sending an email, this way the application
can be certain the email address is valid.
There have been also some smaller improvements to the programming
interface of other packages, most notably itools.vfs, itools.catalog,
itools.web and itools.cms. See the file UPGRADE.txt file for the
incompatible changes.

[ANNOUNCE] Thirty-fifth release of PythonCAD now available
Hi. I'm pleased to announce the thirty-fifth development release of PythonCAD, a CAD package for open-source software users. As the name implies, PythonCAD is written entirely in Python. The goal of this project is to create a fully scriptable drafting program that will match and eventually exceed features found in commercial CAD software. PythonCAD is released under the GNU Public License (GPL). PythonCAD requires Python 2.2 or newer. The interface is GTK 2.0 based, and uses the PyGTK module for interfacing to GTK. The design of PythonCAD is built around the idea of separating the interface from the back end as much as possible. By doing this, it is hoped that both GNOME and KDE interfaces can be added to PythonCAD through usage of the appropriate Python module. Addition of other PythonCAD interfaces will depend on the availability of a Python module for that particular interface and developer interest and action. The thirty-fifth release contains several improvements dealing with the storage and adjustment of user preferences and image settings. The global user preferences are now saved into a file kept in the user home directory, so the settings are now preserved between PythonCAD sessions. Individual drawing settings can be examined and adjusted via a new set of menus and dialogs. These new dialogs are more complete than the single dialog previously used as well as easier to use. In addition to the preference and setting changes, a variety of bug fixes and miscellaneous code improvements are also present in this new release. A mailing list for the development and use of PythonCAD is available. Visit the following page for information about subscribing and viewing the mailing list archive: http://mail.python.org/mailman/listinfo/pythoncad Visit the PythonCAD web site for more information about what PythonCAD does and aims to be: http://www.pythoncad.org/ Come and join me in developing PythonCAD into a world class drafting program!

Re: urllib.unquote and unicode
Martin v. Löwis [EMAIL PROTECTED] wrote: Duncan Booth schrieb: The way that uri encoding is supposed to work is that first the input string in unicode is encoded to UTF-8 and then each byte which is not in the permitted range for characters is encoded as % followed by two hex characters. Can you back up this claim (is supposed to work) by reference to a specification (ideally, chapter and verse)? I'm not sure I have time to read the various RFC's in depth right now, so I may have to come back on this thread later. The one thing I'm convinced of is that the current implementations of urllib.quote and urllib.unquote are broken in respect to their handling of unicode. In particular % encoding is defined in terms of octets, so when given a unicode string urllib.quote should either encoded it, or throw a suitable exception (not KeyError which is what it seems to throw now). My objection to urllib.unquote is that urllib.unquote(u'%a3') returns u'\xa3' which is a character not an octet. I think it should always return a byte string, or it should calculate a byte string and then decode it according to some suitable encoding, or it should throw an exception [choose any of the above]. Adding an optional encoding parameter to quote/unquote be one option, although since you can encode/decode the parameter it doesn't add much. No, the http scheme is defined by RFC 2616 instead. It doesn't really talk about encodings, but hints an interpretation in 3.2.3: The applicable RFC is 3986. See RFC2616 section 3.2.1: For definitive information on URL syntax and semantics, see Uniform Resource Identifiers (URI): Generic Syntax and Semantics, RFC 2396 [42] (which replaces RFCs 1738 [4] and RFC 1808 [11]). and RFC 2396: Obsoleted by: 3986 Now, RFC 2396 already says that URIs are sequences of characters, not sequences of octets, yet RFC 2616 fails to recognize that issue and refuses to specify a character set for its scheme (which RFC 2396 says that it could). and RFC2277, 3.1 says that it MUST identify which charset is used (although that's just a best practice document not a standard). (The block capitals are the RFC's not mine.) The conventional wisdom is that the choice of URI encoding for HTTP is a server-side decision; for that reason, IRIs were introduced. Yes, I know that in practice some systems use other character sets. -- http://mail.python.org/mailman/listinfo/python-list

Well, that sounds like a valid plan, but why would you want to grade the little ones at all, then? What I would most likely do is to publish those small assignments together with a set of tests for each one, and say that they should write programs and make sure their programs pass the tests. If you wish, you could publish two sets of tests, the easy and tricky ones, and have them use easy ones when writing program, and only run it through the tricky tests when they believe the program is bug-free. This can be a very valuable experience! (if you can devise the right tests, of course ;) If you either require the skills they develop doing small assignments in the big assignments, or if you check 2-3 small assignments by hand, you should be able to reduce cheating sufficiently... It's just a matter of making sure they really *do* write programs and that those programs *do* pass the tests. Or just require students to hand in the small assignments, together with the testing output, but do not check them at all (not too many will have the guts to fake the outputs). Then there is a whole range of ideas about peer review in the education community, where you could get students to verify one another's programs...

If you're thinking of representing this as just a flat list, [str1, agent1, str2, agent2, ...], that's a borked way of doing it and you deserve whatever philosophical knots you get into as a result. It's a complete delusion, because even the claimed assumption of list homogeneity is tantmount to saying that Python doesn't encourage (or, arguably, support) ANY way of using mutable heterogenous sequences (such as the example above). It's unfortunate that Python doesn't make the homogeneous/ heterogeneous distinction orthogonal to the mutable/immutable one. Ideally, yes, there would be mutable and immutable tuples, and mutable and immutable lists. Perhaps also even fixed and variable sized versions of these as well. But that would be eight different data types, which is a lot of trouble to go to just to give you something that's precisely tailored to exactly what you want. Some might say it was overkill. Python takes a more pragmatic approach, and provides just two: the tuple, optimised for the case of heterogeneous *and* fixed size *and* immutable -- and the list, for everything else. So it's not really that lists are intended *only* for homogeneous collections, but for anything that can't be represented as a tuple for whichever reason. -- Greg -- http://mail.python.org/mailman/listinfo/python-list
Re: automatically grading small programming assignments
Jeff Rush wrote: For another solution, I wonder whether you could make use of the new Abstract Syntax Tree (AST) in Python 2.5, where you convert the source of an attempt into an abstract data structure, anonymize the method/variable/class names and compare the tree against a correct solution. It would let you quickly handle those students who solved it in a conformist way, and then you'd need to manually review the rest for creatively solving it another way. ;-) You could attempt that kind of solution using previous versions of Python (and the compiler module), but as soon as you want to compare two different ASTs - and I think that unless there's only one obvious solution, they won't be identical - then you need to descend into a world of program transformations that Python doesn't encourage.

IPython 0.7.3 is out
Hi all, The IPython team is happy to release version 0.7.3, with a lot of new enhancements, as well as many bug fixes (including full Python 2.5 support). We hope you all enjoy it, and please report any problems as usual. WHAT is IPython? 1. An interactive shell superior to Python's default. IPython has many features for object introspection, system shell access, and its own special command system for adding functionality when working interactively. 2. An embeddable, ready to use interpreter for your own programs. IPython can be started with a single call from inside another program, providing access to the current namespace. 3. A flexible framework which can be used as the base environment for other systems with Python as the underlying language. 4. A shell for interactive usage of threaded graphical toolkits. IPython has support for interactive, non-blocking control of GTK, Qt and WX applications via special threading flags. The normal Python shell can only do this for Tkinter applications. Where to get it --- IPython's homepage is at: http://ipython.scipy.org and downloads are at: http://ipython.scipy.org/dist We've provided: - Source download (.tar.gz) - A Python Egg (http://peak.telecommunity.com/DevCenter/PythonEggs). - A native win32 installer. We note that IPython is now officially part of most major Linux and BSD distributions, so packages for this version should be coming soon, as the respective maintainers have the time to follow their packaging procedures. Many thanks to Jack Moffit, Norbert Tretkowski, Andrea Riciputi, Dryice Liu and Will Maier for the packaging work, which helps users get IPython more conveniently. Many thanks to Enthought for their continued hosting support for IPython. Release notes - See http://projects.scipy.org/ipython/ipython/wiki/Release/0.7.3/Features for notable new features in this release. Enjoy, and as usual please report any problems.

[ANN] PyInstaller 1.3 released
Hello, PyInstaller 1.3 is out! Grab latest version at: http://pyinstaller.python-hosting.com/ Description --- PyInstaller is a program that converts (packages) Python programs into stand-alone executables, under Windows, Linux and Irix. Its main advantages over similar tools are that PyInstaller works with any version of Python since 1.5, it builds smaller executables thanks to transparent compression, it is multi-platform (so you can build one-file binaries also under Linux), and use the OS support to load the dynamic libraries, thus ensuring full compatibility. Features * Packaging of Python programs into standard executables, that work on computers without Python installed. * Multiplatform: works under Windows, Linux and Irix. (Mac port in development. See /branches/mac on SVN) * Multiversion: works under any version of Python since 1.5. * Dual packaging mode: o Single directory: build a directory containing an executable plus all the external binary modules (.dll, .pyd, .so) used by the program. o Single file: build a single executable file, totally self-contained, which runs without any external dependency. * Support for automatic binary packing through the well-known UPX compressor. * Optional console mode (see standard output and standard error at runtime). * Selectable executable icon (Windows only). * Fully configurable version resource section in executable (Windows only). * Support for building COM servers (Windows only). ChangeLog - + Fix bug with user-provided icons disappearing from built executables when these were compressed with UPX. + Fix problems with packaging of applications using PIL (that was broken because of a bug in Python's import machinery, in recent Python versions). Also add a workaround including Tcl/Tk with PIL unless ImageTk is imported. + (Windows) When used under Windows XP, packaged programs now have the correct look feel and follow user's themes (thanks to the manifest file being linked within the generated executable). This is especially useful for applications using wxPython. + Fix a buffer overrun in the bootloader (which could lead to a crash) when the built executable is run from within a deep directory (more than 70-80 characters in the pathname). * Bootstrap modules are now compressed in the executable (so that they are not visible in plaintext by just looking at it with a hex editor). * Fixed a regression introduced in 1.1: under Linux, the bootloader does not depend on libpythonX.X.so anymore. We've moved --- PyInstaller has a new home: http://pyinstaller.python-hosting.com/ (thanks to the guys at webfaction.com for top-notch free hosting!) We also own a domain name (http://pyinstaller.org) which can be used as a permanent redirector to our home. The mailing list moved as well, it's now at http://groups.google.com/group/PyInstaller.

array, a better shell

I have tried some Python shells: - the vanilla one from DOS - the one from ActivePython IDE - the one from SPE - ipython from a DOS shell But none of them has what I'd like. ipython tries to be a better shell, but I don't want more complexity and more commands/tricks to remember, I want something more interactive, that's simpler and more powerful to use, and not something (much) more complex. Much less things, but the important ones. Beside the vanilla one, I end using the SPE one (because it has colours on Windows too, and it allows you to paste a piece of interactive shell with the leading , SPE removes them automatically. This is very handy). I have also used the shell of Mathematica. It's quite powerful and it can show graphics too inlined, but globally I don't like it fully because it makes editing small programs a pain (for me). Even if I globally don't like the Mathematica shell, it has a capability that I'd like to have in a basic Python shell too. (NOTE: often when dealing with GUI subtle details make a *big* difference, and it's not easy to use words to describe such interaction details.) This Mathematica shell allows you to edit small programs (like 1-15 lines of code) as input blocks, and later you can click on them and edit them. When you press shift-enter inside a block, that small program runs and its output goes just below it (and not at the end of the current shell log). All the Input Blocks can be edited and run again like that (an Input/Output number tag helps to keep things sorted enough). So it's a cross between a normal stupid shell that's essentially an I/O + visual log, and a bare-bone text editor that allows you to edit one script and run it too. Such capability probably needs a Tk/Wx/Gtk window... --- (Such interactive sessions can be saved too, and loaded again (they become complex documents), but such ability isn't necessary into a bare-bone shell that I am describing now. I am describing something as simple as possible). Beside that (new) basic shell capability I think I can appreciate two other capabilities: - Automatically saves the last 20 MBytes of textual input/output log inside a queue file. Material older than the last 20 MB is removed from the top. - Ability to break the computation (or the printing of VERY long things!) without exiting the shell and the kernel (this is from Mathematica too).

Re: tuple.index()
Nick Maclaren wrote: Which is tantamount to saying that Python doesn't support mutable heterogeneous sequences, even though they are not locked out. That is more than just odd - it is almost unbelievable. They are a very basic data structure, after all! What a fuss about something so intangible! :-) If I were you, I'd not worry about taking what people say with regard to the philosophy as a starting point. Instead, it may be more illustrative to consider things from the ground up... * You can put any combination of things into both tuples and lists. * Tuples are immutable, lists are mutable. * You can test both tuples and lists for element membership (x in seq). * You can iterate over both tuples and lists. The contentious issue is why you can't ask where something is in a tuple (the position of an element) whereas you can in a list or even in a string (albeit only with substrings in that particular case). This is where you have to consider how you'd use an immutable sequence like a tuple rather than a mutable sequence like a list. With a tuple, since you can't append to it, you already need to have decided its size and its contents (mutable elements notwithstanding) when you create it. Although it's possible to have thousands of elements in a tuple, you would in most situations need to build such long tuples up either by concatenating existing ones - this is not likely to be particularly efficient due to the need to construct a new tuple for each concatenation of existing ones - or by converting a list into a tuple (questioning the need for a tuple, anyway). So it's unlikely that you'd lightly consider using tuples as an ad-hoc sequence for recording long collections of objects, or that the structure of any tuple you've created is consequently going to be unknown to your program. Even if you were dealing with totally unknown tuples from other sources, the need to query the location of specific elements would probably be much less than just iterating over the tuple or asking whether something is present in it. Of course, one can still argue that querying for the presence of an element is no real substitute for knowing its position. In a program where you define the structure of a tuple in such a way that it makes little sense for a particular element to appear in more than one place - which is where the heterogeneous assertion comes in - knowing the presence of an element is as good as knowing its position (since the program has knowledge of the position implicitly). In a program where you don't define the structure in such a way, the problem situation seems to be as narrow as needing short tuples (as opposed to lists, possibly for use as dictionary keys, for example) whose elements' locations are efficiently discoverable, and where such location information is significantly useful for other purposes. Since tuples are immutable, you can't replace those elements using such location information, leaving fewer and fewer compelling reasons for needing that information in the first place, I would have thought. Perhaps the notion of heterogeneous is best defined in the most general case as a selection of objects unlikely to be considered equal or equivalent, in such a way that the standard test for presence (x in seq) employs such a measure of equality and can suggest (with contextual information) the location of an object by just knowing whether it is present.

Regexp Neg. set of chars HowTo?
Hi!
I want to replace some seqs. in a html.
Let:
a-
b
= ab
but:
xxx -
b
must be unchanged, because it is not word split.
I want to search and replace with re, but I don't know how to neg. this
set ['\ \n\t'].
This time I use full set without these chars, but neg. is better and
shorter.
Ok, I can use [^\s], but I want to know, how to neg. set of chars.
sNorm1= '([^[\ \t\n]]{1})\-\br\ \/\\n' - this is not working.
Thanks for the help:
dd
sNorm1= '([%s]{1})\-\br\ \/\\n'
c = range(0, 256)
c.remove(32)
c.remove(13)
c.remove(10)
c.remove(9)
s = [\\%s % (hex(v).replace('00x', '')) for v in c]
sNorm1 = sNorm1 % (.join(s))
print sNorm1
def Normalize(Text):
rx = re.compile(sNorm1)
def replacer(match):
return match.group(1)
return rx.sub(replacer, Text)

I'd expected, that it was converted into .py-files somehow, which could be imported by my modules. The .egg file should have been copied into your site-packages. Python can import directly from a .egg file (it is a zip archive containing .py files), or you can give easy_install an --always-unzip argument in which case it creates a folder with the same name (including the .egg extension) in site-packages and unzips the egg there. Forcing an unzip can be useful if you want to use tools like pydoc which don't understand imports from zip files.

Re: trouble getting google through urllib
Google doesnt like Python scripts. You will need to pretend to be a browser by setting the user-agent string in the HTTP header. and possibly also run the risk of having your system blocked by Google if they figure out you are lying to them? It is possible. I wrote a 'googlewhack' (remember them?) script a while ago, which pretty much downloaded as many google pages as my adsl could handle. And they didn't punish me for it. Although apparently they do issue short term bans on IP's that abuse their service. For Google, that load must be piss in the ocean.

Re: python-hosting.com projects: dead?
My project was temporarily disabled as well even though I had taken measures to block spam and had committed to svn and edited the trac wiki one day before. I was a bit concerned that maybe webfaction had lost my trac and svn during their house cleaning. But I emailed Remi and he had it going again promptly. They provide a great service for free and they give back to the Python community. They deserve our thanks and our patronage. With regard to how they handled it, I think they chose an effective method. Why should they support projects (for free) that aren't active? So just disable the project to see if anyone cares enough to find out why it's gone. Ever so slightly draconian, but good for keeping a clean house. I'm glad they have done this cleaning work, the server seems much more responsive now; no more errors from trac. !!Dean [EMAIL PROTECTED] wrote: Fredrik Lundh wrote: [EMAIL PROTECTED] wrote: my svn repository and tickets again.

Stani's Python Editor - questions
Hello, I was trying to get answers for these. SPE homepage was down. Then I found it on berlios (http://developer.berlios.de/forum/forum.php?forum_id=12695) but no one answered since 5 days. In fact nobody seems to write in anything to that forum, I presume it is dead. I have no other choice than ask it here. I apologize in advance, they may be silly questions. 1. How can I navigate between opened files? Usually I open 10 or more files at the same time. There is no way to quickly scroll the tabs and select the one that I want. Tabs simply run out of my screen. 2. I tried to use the Browser for navigation but it tells me file is already open and it won't switch to the file. Annoying. 3. I also tried to go to the file using Ctrl+Enter (when the name of the file is written under the cursor). The same problem: it tells file is already open, and it will not switch to the (already opened) file. 4. While running a program from inside SPE, the output window display everything in HTML, including the stdout of the program. I have a program that produces a very nice output when I run it from a terminal. But it is unbelievable what it looks like when I run it from SPE. :-) Especially if you print messages like class __main__.A they will silently disappear from the output screen because they look like an invalid HTML tag. Frustrating. 5. There should be a an option to clear the output panel before running the program anyway. I see no way to clear it at all. 6. When I create a new file and select File/Save as, the dialog window comes up. It is so small that I cannot see the names of the shortest files and it is not resizeable. 7. Whenever I open a file or start a program inside SPE, I get a Failed to display HTML document in ISO-8859-1 encoding error message. 8. The Explore panel on the left comes up for every file that I open. I do not want it to come up by default, because I have screen resolution problems. I did not find any options/preferences to change the above things. Some of the above might be new feature requests. I recently switched from DrPython to SPE. SPE has more functions and it could be much much better than DrPython, but it has big problems. For example, I like that SPE saves the workspace automatically for me. But it takes two minutes to start up SPE, because I have to press the OK button on the ISO8859-1 message for each file that is re-opened. I very like the Browser window, but I cannot use it for navigation. I like the new style save file dialog, but I cannot use it because it is small. I like the code completion.

Re: cross-compiling python: reviewers needed

The patch is available at https://sourceforge.net/tracker/?func=detailatid=305470aid=1597850group_id=5470 (file cross.patch) but it awaits further review. I'm looking for people willing to try this out, and give further review to the patch, so it may be applied to SVN. All you need is a bit of time, and experience in cross-compiling. For various reasons, I don't have the time or resources to really look at your patch in any detail. I was only able to quickly look through it and see how you did certain things, such as specifying a Python build interpreter and splitting up pgen's build rules. I modified the build system in a similar way, so it was reassuring to see similar solutions. Some comments: I noticed that you define a CROSS_COMPILING environment variable so that you know when to use the right tools. Is this a standard variable name in other projects that allow cross-compilation? You rely on an existing Python installation on the build machine. Does this influence the configuration process, or the availability of non-pure Python extension modules? Does the configuration process still cause the tests to be built for the build machine? This seems like a redundant step: ideally, the tests would be run on the target machine in a separate step. The above points are only observations, though. The patch looks like a good first step towards a more configurable build system for Python. It would be even better if, in the future, separate patches could enable custom builds as well. This would, for example, allow minimal Python distributions to be made by stripping out lots of modules that are unavailable or unsuitable for use on embedded hardware.

[ANNOUNCE] Thirty-fifth release of PythonCAD now available
Hi. I'm pleased to announce the thirty-fifth development release of PythonCAD, a CAD package for open-source software users. As the name implies, PythonCAD is written entirely in Python. The goal of this project is to create a fully scriptable drafting program that will match and eventually exceed features found in commercial CAD software. PythonCAD is released under the GNU Public License (GPL). PythonCAD requires Python 2.2 or newer. The interface is GTK 2.0 based, and uses the PyGTK module for interfacing to GTK. The design of PythonCAD is built around the idea of separating the interface from the back end as much as possible. By doing this, it is hoped that both GNOME and KDE interfaces can be added to PythonCAD through usage of the appropriate Python module. Addition of other PythonCAD interfaces will depend on the availability of a Python module for that particular interface and developer interest and action. The thirty-fifth release contains several improvements dealing with the storage and adjustment of user preferences and image settings. The global user preferences are now saved into a file kept in the user home directory, so the settings are now preserved between PythonCAD sessions. Individual drawing settings can be examined and adjusted via a new set of menus and dialogs. These new dialogs are more complete than the single dialog previously used as well as easier to use. In addition to the preference and setting changes, a variety of bug fixes and miscellaneous code improvements are also present in this new release. A mailing list for the development and use of PythonCAD is available. Visit the following page for information about subscribing and viewing the mailing list archive: http://mail.python.org/mailman/listinfo/pythoncad Visit the PythonCAD web site for more information about what PythonCAD does and aims to be: http://www.pythoncad.org/ Come and join me in developing PythonCAD into a world class drafting program!

tkFileDialog closes main application
Hello,
I wish to collect 4 files from a user. So I have decided to use
tkFileDialog askopenfilename. My problem is that after a few file
selections the root window is destroyed (the whole program just dissappears)
I have created a simple example and was able to reproduce the same thing
with this. I've just started using tkinter so I have no idea what I may
be doing wrong. If anyone has any ideas please let me know.
If you run the following code, just click the Browse button, and select
a file. Do this repeatedly and for me after the sixth or seventh time
the window shuts down.
BTW, I'm using python 2.4 on Windows XP. Thank you for any help.
from Tkinter import *
import Pmw
import tkFileDialog
import os.path
filepath = 'C:\\Documents and Settings\\admin\\Desktop\\'
class App(Frame):
def __init__(self,master):
Frame.__init__(self, master, bg='gray')
self.enttxt = StringVar()
lbl = Label(self,text='File 1:')
lbl.grid(row = 0,column = 0,sticky = W,padx = 5,pady = 5)
self.e1 = Entry(self,textvariable = self.enttxt,width = 50)
self.e1.grid(row = 0,column = 1,columnspan = 3,sticky = W,padx

btn = Button(self,text='Browse ...',width = 12,

btn.grid(row = 0,column = 4,sticky=W,padx=5,pady=5)
def browse(self):

your opinion about psycopg vs pygresql
Hi all, I'm playing a bit with PostgreSQL, in which I've set me the target to create a python script which with user input creates a new user role and a database with that owner (connecting to template1 since I know that at least that db exists). Ok so I installed PostGreSQL and pygresql since it looked like that this is endorsed by PG, I had some trouble with the DB-API2 (complains about there is already a connection to template1, even when I closed and deleted the connector) so I solved it by using the pg api. But I was intrigued by this problem and started googling and by that time I've noticed that python projects like Django seem to favor the psycopg module. So I installed that one (the 1.1 version, since Django uses that too) and it looked like it has the same problem of creating a user after a database, I'm sure that there is a user error in there somewhere :-) However, given the choice, what in your opinion would be the reason why someone would chose one over the other? Now I know this could easily get into a flamewar, so if you comment (but please do so) I'll still investigate that, since at this moment I don't even have a clue how they differ and on what reason, why does PostgreSQL seem to favour pygresql and Pythoneers psycopg? Thanks in advance. -- mph -- http://mail.python.org/mailman/listinfo/python-list

No-one would use an implementation with no GC. The issue with specifying it is: How would you do it? The memory used by a program is an aspect of the language implementation and the system the program is running on, so how can it be defined in a useful way? You could say for example Storage allocated for an object is released when the object is no longer visible and memory usage is high. But how do you define how high memory usage should be? You could say when memory is almost exhausted, even that is difficult to define. Then you could have the situation where someone creates a lisp compiler than emits FPGA netlists, how do you check something like this? None of this would be in the spirit of the spec, which doesn't even define memory AFAIK. The spec deals entirely in matters of the language and it's appearance to the programmer. For what it's worth I think the C spec is the same, and says nothing about actual memory usage. -- http://mail.python.org/mailman/listinfo/python-list
