Similarly, there could be a
database design tool to create a database, and save SQL/DML
expressions into an XML config file.
Why so ? What's wrong with a plain SQL file ? We already have a language
for RDBMS schema description, and the schema description is itself
stored in the RDBMS catalog so the SQL description can be regenerated
from the RDBMS. I just don't see the point of storing all this in XML.
Then you create the RDB command
objects by loading the XML in your favourite language.
I think programming languages are intended for describing neither relational
databases nor GUIs.
SQLAlchemy is an interesting attempt at integrating the relational model
in a programming language.
Ok, I don't mean neither of us is necessarily right and the other wrong
- different POV, mostly, so I guess we can at least agree to disagree !-)
Plain SQL does not have a structure to easily handle metadata. XML has
several parsers, transformators like xmlto.
I am not going to reimplement relational stuff in XML or any
programming language. In my approach relational model is described in
SQL, processing is in a programming language, and XML is used for
interchange data. That data is actually SQL, and metadata to create
documentation.
I have looked into SQLAlchemy. I have seen this:
users_table = Table('users', metadata, Column('id', Integer,
primary_key=True), Column('name', String), ...
session.query(User,
Address).filter(User.id==Address.user_id).filter(Address.email_address=='[EMAIL
PROTECTED]').all()
users_table = Table('users', metadata, Column('id', Integer,
primary_key=True), Column('name', String), ...
...and I do not like it.
My favourite programming language is python because of its simple and
practical syntax. SQLAlchemy is something different, something like
what I do in full time, and something I am fed up with.

Then you create the RDB command objects by loading the XML in your favourite language. I'd agree that XML makes a good interchange representation which saves everyone from having to parse various things, but having worked a bit with relational databases and having had to actively manage their schemas, I have to say that my primary representation for a schema is SQL/DDL, and that my primary representation for queries is also SQL. Now, there's a lot to be said for making that SQL more consumable, and I've done a little work on converting SQL to XML (as have many others) in order to make life easier for, say, tool authors, and I'd even go as far as saying that it should be possible to convert XML back to SQL, but in doing so there would potentially remain a need for the XML dialect to be as expressive as SQL, which then means that you have to replicate SQL in XML. I think programming languages are intended for describing neither relational databases nor GUIs. The above discussion is somewhat tangential to what you've done, though, and I certainly didn't mean to say that the use of XML was in any way wrong, especially in the way you've been using it. I suppose that when you state the above about programming languages, you actually mean languages other than SQL. Even so, I'd much rather use SQL to describe a database table than one of the many different Python- based, class-plus-attributes representations so beloved of the various object-relational mappers. I look forward to seeing where you take your project in future, however. Paul I agree more than you thought. I do not want to replace SQL with XML either. I only use XML to interchange data (SQL/DML) between the database designer (tool) and the application interface in order to create a specific database interface for a certain database. It is the focus of database design using different RDBMS-s and different programming languages. There is an other reason for XML. At this point my XML structure contains the SQL/DML expressions as you use it in sql clients, and some metadata to generate documentation using XSL transformation. That's why I provided that sqlface.xsl in the src directory. Yes I have to relocate DTD and XSL from the python source directory. Relational stuff stays in the relational language SQL. Data processing, and business logic goes into a programming language like python. Otherwise I plan to support other languages with such an SQL interface.

I've never quite understood why folks want to repeat the database's metadata in XML files. I've gotten much better results just using plain ol' SQL throughout, sprinkled in with generated-on-the-fly SQL. 1. A select clause identifies what is coming back from the db in the cursor's description. 20 lines of code shoves that in a dictionary for each row for any result set. 'Select * from table' works 90% of the time for 1 table queries. What does XML add? 2. Inserts and deletes are relatively trivial to derive from INFORMATION SCHEMA lookups on any given table and templates can be generated for them. Updates are admittedly less trivial, but not horribly so. 3. Query parameters can be added by simple %(colname)s embedded in the query templates.That works great with dictionaries. You can extract them with a regular expression and replace them with '?' and a list, if your DB-API flavor requires that. 4. Plain ol' SQL can be cut and pasted in a query editor and can be tested there. 5. If you unit test somewhat aggressively, any db-schema changes will result in unhappy queries dying because they don't see the columns that they expect in the resultsets. That keeps your Python code in synch without feeding a layer of XML cruft. 6. XML is plain nasty for simple local usage where you don't need to communicate with a 3rd party app or module. Conversely, XML is great when you need to communicate data somewhere else, potentially with recursive and nested structures. 7. ANSI SQL is actually quite portable, if you know what to avoid doing. 8. Last, but not least. Performance. In complex processing on a database with large volumes, the last thing you want to do is to fetch data to your client codeline, process it there, and spew it back to the database. Instead you want to shoot off series of updates/deletes/insert-selects queries to the server and you want to rely on set-based processing rather than row-by-row approaches. How do ORMs+XML help here? My biggest hassle has been managing connection strings and catching the weird Exception structures every Python db module figures it has to re-implement, not the SQL itself. Granted, if this were Java, you would need special data transfer objects to encapsulate the results. But is not Java. And, also granted, I _enjoy_ coding in SQL rather than trying to hide from it, so YMMV. Bottom line: SQL is extremely dynamic in nature, even more so than Python. Why shackle it to static XML files?

So I'm wondering, except for the callable's exact type (bound method vs function vs functools.partial object) is there any other difference and a reason to prefer one over the other ? Consistency ? Possibly performances (NB : not benchmarked - might be worth a little homework to check this out) ? If not, functools.partial() seems more readable than calling explicitly the descriptor. Perhaps is it just me starting to getting senile and resistant to new ideas, but while it does indeed work, I see the partial() solution as a WTF.

Because in Python there's no support for bytes and even for xoring bytes, so I used a workaround: I cycle on the two strings to be xor-red for every char in the strings convert one char on integer and then xor them; (ord) insert one char in the result, transforming the previous integer in char (chr) I suppose that ord() and char() are the main problems of my implementation, but I don't know either way to xor two bytes of data (bytes are represented as strings). For more information, see the code attached. How should I decrease the execution time? Thank you from __future__ import division import random import time import sha import os class Encoder(object): def create_random_block(self, data, seed, blocksize): number_of_blocks = int(len(data)/blocksize) random.seed(seed) random_block = ['0'] * blocksize You possibly mean '\0' i.e. the byte all of whose bits are zero. for index in range(number_of_blocks): if int(random.getrandbits(1)) == 1: getrandbits(1) produces a *long* with one random bit. Any good reason for preferring this to randrange(2) and randint(0, 1)? So there's a 50% chance that this block will be XORed into the result; is that what you intend? block = data[blocksize*index:blocksize*index+blocksize] You don't need to slice out block, certainly not so awkwardly. for bit in range(len(block)): Perhaps you mean byte_index, not bit. On my assumption that range(len(block)) is invariant: calculate it once. That assumption is incorrect, so is your code for calculating the number of blocks; it ignores a possible short block at the end. random_block[bit] = chr(ord(random_block[bit])^ord(block[bit])) The chr() and one ord() are utterly wasteful; leave random_block as a list of ints and do the chr() thing in the return statement. # workaround per fare xor bit a bit di str; xor e' solo supportato per int - ord return ''.join(random_block) this will become return ''.join(map(chr, random_block)) or return ''.join(chr(i) for i in random_block) as taste or speed dictates :-) So the whole thing becomes [not tested]: def create_random_block(self, data, seed, blocksize): datalen = len(data) assert datalen % blocksize == 0 random.seed(seed) random_block = [0] * blocksize block_range = range(blocksize) for start in xrange(0, datalen, blocksize): if random.randrange(2): for x in block_range: random_block[x] ^= ord(data[start + x]) return ''.join(map(chr, random_block)) Looks slightly more athletic than before :-) BTW, +1 misleading subject of the week; it's not XOR that's slow!!

Python equivalent to SharePoint?
We've got a client who has been planning to use SharePoint for managing their organization documents, but has recently dropped that idea and is looking for an alternative. Is there any Python package with similar functionality? I confess that I've never used SharePoint myself, and what I know about is mainly from these sources: http://en.wikipedia.org/wiki/SharePoint http://discuss.joelonsoftware.com/default.asp?joel.3.66103.7 I found a reference to CPS, but its developers have dropped the Python source to rewrite it in Java.

RE: Kicking off a python script using Windows Scheduled Task
Does anyone know how to properly kick off a script using Windows Scheduled Task? The script calls other python modules within itself. HERE'S THE CATCH: I am used to running the script directly from the command window and the print() is very handy for us to debug and monitor. When running the task from Windows Scheduled Task, we'd like to be able to view the command window and keep it up after the Task has completed... I used the commands CMD /K cd C:\testdirectory\script_RunTests python AutomatedTestRun.py but when AutomatedTestRun.py calls other python modules, we don't see output. Import os and add os.system(pause) at the end of AutomatedTestRun.py to keep cmd open. As far as not seeing any output, I haven't had any trouble with that before. Maybe you're doing something unusual? Have you tried using the logging module, rather than print? Might be more useful for what you're trying to do.

It looks to me like what you're sending is correct. Debugging
suggestions --
- Set up a Web server on 127.0.0.1 and see what that server receives
when your Python code connects to it. Maybe you're not sending quite
what you think.
- Try emulating your Python code with wget or a similar command line
tool that lets you set headers.
- Sniff the conversation you're having with google using Wireshark.
Maybe you're getting redirected by the remote server.

Ooo 3.0 Python user macros
Has anyone been able to run user-defined Python macros in OpenOffice.org 3.0? I had one in ~/.ooo-2.0/user/Scripts/python/try.py which did work under Ooo2.x. So I put the same thing in ~/.ooo3/user/Scripts/python/, but it will not show up in any macro dialog in Ooo 3.0. The provided example macros seem to work: under the Tools - Macros - Organize Macros - Python... menu, there is an entry named OpenOffice.org Macros, and I can run the macros that are listed in there.

xor: how come so slow?
Hi, I'm trying to encode a byte data. Let's not focus on the process of encoding; in fact, I want to emphasize that the method create_random_block takes 0.5s to be executed (even Java it's faster) on a Dual-Core 3.0Ghz machine: took 46.74679s, avg: 0.4674679s Thus I suppose that the xor operation between bytes raise the execution time to 0.5; why I suppose that? Because in Python there's no support for bytes and even for xoring bytes, so I used a workaround: I cycle on the two strings to be xor-red for every char in the strings convert one char on integer and then xor them; (ord) insert one char in the result, transforming the previous integer in char (chr) I suppose that ord() and char() are the main problems of my implementation, but I don't know either way to xor two bytes of data (bytes are represented as strings). For more information, see the code attached. How should I decrease the execution time? Thank you from __future__ import division import random import time import sha import os class Encoder(object): def create_random_block(self, data, seed, blocksize): number_of_blocks = int(len(data)/blocksize) random.seed(seed) random_block = ['0'] * blocksize for index in range(number_of_blocks): if int(random.getrandbits(1)) == 1: block = data[blocksize*index:blocksize*index+blocksize] for bit in range(len(block)): random_block[bit] = chr(ord(random_block[bit])^ord(block[bit])) # workaround per fare xor bit a bit di str; xor e' solo supportato per int - ord return ''.join(random_block) x = Encoder() piece = os.urandom(1024*1024) blocksize = 16384 t1 = time.time() for l in range(100): seed = random.getrandbits(32) block = x.create_random_block(piece, seed, blocksize) t2 = time.time() print 'took ' + str(t2-t1) + 's, avg: ' + str((t2-t1)/100.0) + 's' -- http://mail.python.org/mailman/listinfo/python-list

I confess that I've never used SharePoint myself, and what I know about is mainly from these sources: http://en.wikipedia.org/wiki/SharePoint http://discuss.joelonsoftware.com/default.asp?joel.3.66103.7 The Wiki vs. CMS thing is relevant, even though I imagine that corporate types like to pooh-pooh the idea of Wikis, preferring as they do to use their CMS or intranet solution as yet another shared folder for their Word documents. What I know from experiences trying to build a willing editing community around the EuroPython site was that people didn't like to stray anywhere near CPS, but people could be coerced into editing Wiki content; the PyCon UK site had even more contributions from random conference attendees. Of course, a corporate CMS typically involves the imposition of such a system on employees - that's one way not to bother about user acceptance since everyone implicitly says yes once the roll-out begins - but as one commenter on Joel's article notes, even the fanciest solutions require a degree of willing maintenance, and if it all starts to rot then the whole point of introducing such a system is undermined. I found a reference to CPS, but its developers have dropped the Python source to rewrite it in Java. That's disturbing, and I don't want to recommend an abandoned platform. Anything else I should consider? There may be other solutions not included on the page I mention above. I remember being shown SharePoint a few years back by a fellow consultant, and apart from the fancy drag-and-drop layout tools I was strongly reminded of Slashdot, of which the consultant was naturally unaware. At that time, for the basics of a community site such as certain kinds of intranets, Zope plus Squishdot would have been acceptable, but any absence of steep licensing costs isn't necessarily an advantage in the consulting business since such stuff usually gets passed onto the brand-obsessed customer. With regard to proper document management, I think we'll increasingly see developments around the revitalised area of version control systems and their integration with Web-based solutions.

I have written a simple code to upload a file via ftp to remote server
-
import sys
import ftplib
host=sys.argv[1]
username=sys.argv[2]
passwd=sys.argv[3]
filename=sys.argv[4]
print host,username,passwd
ftp = ftplib.FTP(host,username,passwd)
fd=open(filename,'rb')
ftp.storbinary('STOR filename',fd)
---
I am passing file name in cmd line arg. but I have no idea how to use
filename variable value in ftp.storbinary('STOR filename',fd) ?

I would just use UTF-8 and be done with it. Set your editor to write UTF-8 files, set the correct #coding at your python script, make sure your terminal supports outputting UTF-8 characters (and your font has the correct glyphs) and everything should be fine. No trickery required. Even for Python 2.x, the only extra thing needed was the u kind of strings. No other trickery in sys.stdout required. What platform do you use?

Multimethods do the thing you're looking for. Google: 'python
multimethods' gives:

from mm import multimethod
@multimethod(int, int)
def foo(a, b):
...code for two ints...
@multimethod(float, float):
def foo(a, b):
...code for two floats..
It is especially good if you're using inheritance. You could also
collect the names of the types, and call a function by name:
(untested)
fname= a.__class__.__name__+ '_'+ b.__class__.__name__
or
fname= re.sub( '[^a-Za-z0-9]+', '', str( type( a ) ) ) + same
type( b )
ffunc= getattr( namespace, fname )
or build a dictionary.
(untested)
f= {}
f[ int, int ]= compA
f[ int, str ]= compB
...
ffunc= f[ type( a ), type( b ) ]
What's your favorite?

If all your comparison methods do more or less the same (even if not but
then it will be kinda less useful for complex operations) you could use
dictionary-based dispatching. You would basically construct a dictionary
of type-comparator mappings, like this::
dispatch = {
int: int_compare_function,
str: str_compare_function,
}
And dispatch according to the other object's type::
def __cmp__(self, other):
return dispatch[type(other)]()
(Assuming good faith and just throwing a `KeyError` for unimplemented
types.)
If you just needed to dispatch on a special attribute depending on the
other object's type, you could redesign the dispatch dictionary to be a
type-attribute mapping and go somewhere along this way::
dispatch = {
int: 'value',
str: 'name',
}
def __cmp__(self, other):
return cmp(getattr(self, dispatch[type(other)]), other)

Re: xor: how come so slow?
Few suggestions for your code: - Use xrange instead of range. - Loop over lists where you can instead of their indexes. - array.array(B, somestring) may help you because it gives a byte view of a string. - Using psyco helps a lot for such kind of code. - I think numpy arrays can contain text/chars too, so it may offer you ways to speed up your code a lot. - Generally Python is fit to download pages from the net or to act as glue between different subsystems, or to do bulk string processing, etc, but for grunt low-level works like this it's often too much slow, and you can use other lower-level languages. - You can use a lib already written, or use an extension, for example you can try ShedSkin, or Pyd.

Re: replace mothod for only one object but not for a class
Hi hofer a écrit : I have multiple objects all belonging to the same class (which I didn't implement and whose code I don't want to modify) Now I'd like to change one method for one object only (after it has been created) without adding any overhead to the call of the other object's methods.

Re: IDE Question
You can find a list and several reviews on http://wiki.python.org/moin/IntegratedDevelopmentEnvironments I think Wing IDE (http://www.wingware.com/products) is generally thought to be the most sophisticated one; but it's neither open-source nor gratis (they do let noncommerical open-source devs get a free copy though). From what I've heard anecdotally, most Pythonistas don't use IDEs, instead opting for just a text editor (often vim or emacs). So the answer to your question is probably None.

Re: Can Python fix vcard files?
2008/10/15 [EMAIL PROTECTED]:
Just out of curiosity, are the line endings CRLF perchance? If so, try
changing the replace call like this:
cooked = uncooked.replace('\r\n ', '')
Apparently they were CRLF. Actually, I think that is part of the Vcard
spec. Now, it seems that I have a few other problems, but they seem to
be bugs in Kontact.
Thank you very much for the help. I've learned how to open and save
files, and how to search and replace text. I probably could have
gotten that far after a some time googling, but you've probably saved
me a good day or two. Furthermore, I would have had trouble finding
out which libraries to include at the head. Thanks!

Overloading operators
Hi, in a project I'm overloading a lot of comparison and arithmetic operators to make them working with more complex classes that I defined. Sometimes I need a different behavior of the operator depending on the argument. For example, if I compare a object with an int, I get a result, but if I compare the same object with a string, or another object, I get another result. What is the best way to do this? Shall I use a lot of if...elif statements inside the overloaded operator? Or is there a more pythonic and dynamic way? -- http://mail.python.org/mailman/listinfo/python-list
Re: PyGUI as a standard GUI API for Python?
hello_loader.py is the main err um i just double- checked, so i'd be able to advise you and... err... the problem i described (with the GridTest) seems to have... gone away!! There are lots of references to PyGTK classes in there. yes, that's because i had started with the gtk port, and was going through the examples one-by-one removing them and replacing them with qt. as i only got up to the Info tab of KitchenSink, there is still quite a bit to do. i _say_ quite a bit - but it's only about ... 16-24 hours of work. pyjamas is surprisingly small. Is there a way to select Qt instead of GTK? sorry! removing them :) Hacking the code a bit, :) I can run the hello_loader.py example. The items on the left do indeed overlap. It looks like the minimum size of the labels aren't being respected for some reason. yeah. and the pyjamas ui.HTML() class is based on a Qt.QLabel(). if that can be fixed, then there's a fair good reason to continue. Yes, there are ways to relate the height of a widget to its width, and there may well be a way to do that for a standard text widget, but it might involve some experimentation with the underlying text document. *sharp intake of breath* :) yehhh, i did word-breaking by wrapping groups of 8 letters at a time in floating-divs once, to simulate word- breaking in a situation where the column width was 200px and people were putting in web site addresses of 50 chars in length yukk. -- http://mail.python.org/mailman/listinfo/python-list

Re: IDE Question
Thanks for all of your responses. I did forget to mention that I do use Notepad++ for just about everything. My larger scripts I use that and just say the hell with the auto-complete and the call-tips. I lived on that wiki page and actually still do waiting to see if something new was going to be added. It is safe to say that my definition of the perfect IDE would be one that has reliable call-tips and auto-completions. I have been doing Python for about 2-2.5 years now. Prior to using IDLE for modules that I am unfamiliar with I have always used NP++. Before Python was my primary language, it was straight VB, VBA, VBScript, etc... That should give you some insight to where I am coming from. Steve P On 10/15/08, Steve Phillips [EMAIL PROTECTED] wrote: Hi All, I am just wondering what seems to be the most popular IDE. The reason I ask is I am currently at war with myself when it comes to IDE's. It seems like every one I find and try out has something in it that others don't and viceversa. I am in search for the perfect IDE and after many months of searching, I always come back to IDLE to do what I need to do. I want to use Komodo badly but the one issue I have with that is sometimes the auto-complete works and other times it doesn't. Even if I carbon copy a script.

With emacs, I can have multiple files open in one window, with the window split (I don't remember eclipse being able to do this, although it allowed multiple files in their own tabs), and I can customize the actions of the editor on the fly, without restarting it, in a variant of LISP. That may be possible in Eclipse, I don't really know. I used to use Eclipse and pydev, but once I learned my way around emacs, I haven't gone back to it for anything. I probably would if I did any coding in Java - but I don't. I'm exponentially more productive with emacs while writing python code than I ever was with Eclipse. Add to that the degree to which emacs is customizable (just about everything that the editor does can be customized, you can jump quickly to the source of the functions you're running while editing, you can easily patch behavior in before or after specific function calls, you can easily define keyboard macros and bind them to keystrokes, and / or save them for future use, you can easily create keystrokes that correspond to interactive filling out of templates - skeletons, etc), and I really don't see how someone could think that Eclipse is anywhere near being a replacement for emacs. Not to mention that I don't need to have X installed to run emacs if I don't need it. I may be wrong about the capabilities of Eclipse, as I haven't used it in about a year, and emacs certainly has it's own set of quirks and annoyances - one of which being the very steep learning curve. Watching the screencasts linked in the blog post you linked to, I might prefer Eclipse to emacs if I wasn't very used to never touching a mouse, or if I was developing under windows. With my editing mindset the way it is right now, when I see that, I just see a lot of wasted screen space, and a lot of wasted time doing things like intellisense. Also, the blog post didn't really give any reasons as to _why_ the person switched over, other than that they were impressed with Eclipse. Meh, I'm not talking trash on Eclipse - it's a fine tool if it fits how you work with text / code. It's just not for me, and I would feel crippled while using it if I switched back to it. I used IDEs like that for a few years, but after about a month and a half of using emacs, I haven't looked back. I even use it as my IRC client when I jump on IRC. I do think that people should try a variety of styles of editors to find what works best for them though - although it does take a lot of time to learn your way around 3 or 4 different editors, once you find what fits with you, you will probably get a huge boost in productivity. -- http://mail.python.org/mailman/listinfo/python-list

Re: problem using ctypes with MMX intrinsics
dcharno wrote: Is it possible to use ctypes with a shared library which uses MMX/SSE intrinsics? I can load the library and access functions inside it, but I getting a seg fault when I hit one of the intrinsics. I'm wondering if there might be some sort of stack alignment problem. I am using gcc version 4.2.3 and Python 2.5.2 on Ubuntu 8.04. Any suggestions would be helpful. Well, stack alignment would be a problem with how the shared library gets compiled, nothing to do with ctypes (I think). However, if you are passing in arrays from ctypes, *they* may also be misaligned. Try to check the addresses of the ctypes values you are passing in. I'm not entirely sure how to do that, though. -- Robert Kern I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth. -- Umberto Eco -- http://mail.python.org/mailman/listinfo/python-list
