Is this right? it seems like nothing is any easier (except having variables locally). Is this right? Should I be creating more classes for different things or what? Use the method that works best for you. If you like the procedural approach more then don't worry about being object oriented. The good thing is that python is multi-paradigm so if custom objects don't make your life easier then just forget about them :) One great benefit to classes is the ability to take a generic class and then subclass it. Or the ability to instantiate various objects from one class. Say you have a dog class. If you pass in the correct data, you can instantiate a dalmatian, a Labrador or a mutt.

The only way to kill a thread is to have the spawned thread have
some kind of passed in argument which will trigger it to shut down.
You could have the thread read a file or file-like object periodically
(like a timer) and if it meets some condition, have the thread quit.
It's kind of like a subscription process. The thread subscribes to the
main program and can accept signals. I suggest that the OP read the
docs on threads:
http://docs.python.org/lib/module-threading.html
Of special interest to this user:

I have messed with KillProcName, a PyWin32 script with limited
success. There's also the following snippet which is Windows only and
works for some processes and not others (i.e. unreliable):
subprocess.Popen('taskkill /s %s /im %s' % (computer_id, proc))

Re: Does Python cache the startup module?

When I ran the program, the program started to leak memory like a sieve. I then changed the name back again, and the problem went away. This looks very much like some sort of weird caching behaviour to me. I've tried deleting the .pyc file and even re-booting, but I can't make the problem go away! Can anyone confirm that this caching happens? And if so, is it documented anywhere? TIA You can run a dir() in the GUI IDLE or the command line IDLE and see what's currently cached, so to speak.

Tabnanny errors when Migrating Python 2.4 code to 2.5

Thanks Mike,
you have provided another option.
But my question has not been answered yet. The reason, why I use
os.system(), is that I want to avoid accident file deletion by writing a
script. My real script looks like:
Technically speaking, the shutil module's copytree function will not
delete ANYTHING if the destination already exists. It will just fail.
You could catch the failed copy with a try/except that prints an
appropriate message detailing the error.
# 1. Funtion to execute a command in DOS-console
def execCommand(cmd):
if DEBUG_MODE:
print 'DOS ' + cmd;
else:
os.system(cmd);
# 2.1 Creates temp folder. Removes it first, if it exists.
if os.path.exists(tmp_folder):
execCommand('RD ' + tmp_folder + ' /S /Q');
execCommand('MD ' + tmp_folder + '');
# 2.2 Copies all files to the temp folder, that are going to be put in
package.
for source_folder, dest_folder in folders_array:
if not os.path.exists(dest_folder):
execCommand('MD ' + dest_folder + '');
execCommand('XCOPY \' + source_folder + ' ' + dest_folder + ' /Y');
The benefit is that, when I set DEBUG_MODE=True, I can see what will be
executed. So that I can make sure that my script will not delete any
other important files by accident.

Since then, it seems, I have made the wrong decision. For example I have module A that imports module B. Each one does this: gettext.install( domain, localedir, unicode = True ) lang = gettext.translation(domain, localedir, languages = [ loc ] ) lang.install(unicode = True ) (where doman is the name of the module, so A and B) The problem is that domain A loads and then import B happens and so the lang reference (I think) gets replaced by domain B -- the result is that module A can only translate strings that are in domain B. How does one 'merge' gettext.translations objects together? Or is that insane? What's the best way to handle a project with multiple domain.mo files?

The crashes are not Python exceptions, but rather are reported by Windows as errors in pythonw.exe. (Of course, the error messages themselves contain absolutely no useful information.) This happens whether I run them from the command prompt or from IDLE (although IDLE itself never crashes). Further, the crashes occur at unpredictable times; sometimes the program will crash almost immediately upon startup, while at other times it will run for a while and then crash. Also, I'm not sure whether this has anything to do with my problem, but Machine H also has Python 2.2 installed on it, while Machine W does not.

At the moment I am trying to write a Python program that will run in the background and execute a series of commands whenever I switch between windows (my OS is Windows XP). For example, I want my program to do something when I switch to my Firefox browser, and then do something else when I switch to a certain sub- window in Photoshop (which has a certain title, and a certain photo associated with it), then do yet another thing when I switch to another sub-window (with a different title and photo) within Photoshop. The particular actions will be based on the window's title. I've already figured out how to retrieve that, using GetWindowText(GetForegroundWindow()) from the win32gui module. My question is, how can I detect when the user switches between windows? I haven't been able to figure that part out yet. Searching the group didn't give me any answers. Your help is greatly appreciated. Thanks! Assaf. What you most likely want to do is run the win32gui call inside an infinite loop. Something along these lines: # untested code import time while True: winTitle = GetWindowText(GetForegroundWindow()) if winTitle == 'some string': # do something time.sleep(1) # nap for a second This will check once a second to see what window you have up. You'll probably want to set some kind of sentinel value when it does something to the current window so it doesn't repeatedly do that something each second. Thus, the if-then logic will need to be more complex, but this should get you going. HTH Mike -- http://mail.python.org/mailman/listinfo/python-list

past, however I have to move to SQL2005 and SQLEXPRESS databases now.
I've tried the following but with no luck [this is what i used in the
earlier incarnation except the Provider resource was SQLOLEDB.1]
Conn = Dispatch('ADODB.Connection')
Conn.ConnectionString = Provider=SQLNCLI;Server=10.1.1.2;
Database=csrctest;Uid=bill;Pwd=bill
print Conn.ConnectionString
try:
print 'trying to open'
Conn.Open()
etc.
All I ever get to is the trying to openline, then it times out.
I have tried all of the following combinations too:
Provider=SQLNCLI;Server=localhost;Database=csrctest;Uid=bill;Pwd=bill;
Provider=SQLNCLI;Server=localhost\SQLEXPRESS;Database=csrctest;Uid=bill;Pwd=bill;
The SQLEXPRESS database for testing purposes is on my home PC
[10.1.1.2]
Any clues s to where I am going wrong?
Look forward to hearing from someone, anyone!!
Kind regards
Bill
You might try pymssql:
http://pymssql.sourceforge.net/
I've only used it with MSSQL2000, but according to the website, it
should work with 2005 too.
If you wrapped your database interface with SQLObject or SQLAlchemy,
then (as I understand it) the sql connector module can be swapped out
with little to no work. I hope to move to one of those sooner or
later:

Re: error with wxPython2.8-win32-unicode-2.8.7.1-py25.exe

The newer versions of wx are not supposed to be imported in this way: from wx import * The current correct way is to just import wx. I am not sure when this was started, but it was more than a year ago. Most of the time, from package import * is NOT recommended as it can unintended consequences, such as poisoning the namespace. For example, if you did this with a package that contained an object called foo and you did this: foo = 2 Then you just reassigned the foo that was imported.

Passing arguments to exe
I have created what amounts to a simple GUI email sending program using Python + wxPython. I have modified the mailto registration in the Windows Registry so that it launches the script when someone clicks on someone's email link in a web page. While this works great if I create a convoluted path command as the registry entry and pass in the email argument to the script, it doesn't work at all if I turn my python file into an exe using py2exe. How does one get a python file to accept arguments when said script has been turned into an executable? I'm sure I'm just missing something obvious. I am using Python 2.4 on Window XP SP2.

It has a lot of code for now and I've only made interface. So I've tried to split code into separate files and in windows as I remember worked file when i wrote eg. import myFile but now in Ubuntu it says Module not found. (I'm using Ubuntu and I've installed python 2.5 and wxPython 2.8.4, and I'm using GedIt as my favorite text editor). The question is how to make this work (files are in the same folder) Not sure what is going on here from this description. You may need to use the sys module and add the path to your module temporarily. import sys sys.path.append(//path/to/myFile) Second question is about import wx. When i separate code into files i have to write import wx into every file because all of them contains some part of the interface. Does that make my program bigger than putting everything into one file and use only one import. Thanks in advance. No, importing wx in multiple files does not make it bigger. In fact, as I understand it, Python will only import a module if it's not already in the namespace. So if you import wx in your main module and then import it again in some sub-module of yours, Python won't actually import wx the second time, but will just use the one that's in the namespace already.

If the script is expecting its arguments in sys.argv, I would expect that to work with an executable also. My guess is that you are falling foul of some argument-quoting problem. I also guess that you have not tried something like the following at the start of your script: print your_log_file, sys.argv:, repr(sys.argv) and run it both as a script and an executable. I do have my script set up to find its arguments in sys.argv. And no, I don't have that print screen. As mentioned above, I don't have a console window open when the exe runs, so I won't see any output from it. I'll have to modify it to do that when I'm back at my work PC. Have you tried running the executable stand-alone e.g. Start | Run, type in your_exe_file [EMAIL PROTECTED] or whatever the argument(s) are? No, but that's a good idea. Why didn't I think of that!?

sqlite weirdness
Hi, I am trying to use sqlite to create a local database for an application I am writing and I am getting some screwy results from it. Basically, I have a set of values in the database and I am trying to select a date range and sum those values. My problem is that it only sums up every other date range and ignores the in between ranges. Here's the table structure: sql = '''CREATE TABLE tbl_TimeEntries (dateworked DATE, empid INTEGER, reg REAL, ot REAL, ce REAL, hol REAL, sklv REAL, vac REAL, ct REAL, conv REAL, misc REAL, comments TEXT, PRIMARY KEY (dateworked, empid)) ''' I have data in it from 12/18/2006 - 01/26/2007.

Very short story: sqlite doesn't have a native date type (look at the results it's returning (e.g. u'12/18/2006')), and is doing a *string* comparison.

Sorry, I need a better proof-reader.
When I run that code, the output gets to ~26 and then IDLE (or the
shell, I'm not sure which) hangs and there's zero CPU activity in the
pythonw.exe process.
Also, I should say that the the idea is that the huge iteration should
timeout after 5 seconds. I only gave it a 1000 range because I
didn't know how fast it would get through the loop. Perhaps you stopped
it before the timeout triggered?
Cheers,

No...I ran it for at least 30-60 seconds. Making a thread stop on
command is a pain though.

The layout doesn't look as nice as for the others. I've seen some powerful stuff done in Tkinter. While I prefer wxPython, it's still a valid choice. If you browse the list, you'll notice that Tk is going to be (or just has been) upgraded, so Tkinter should start looking better soon. wxPython seems to be the first-hand choice for people doing W32-programming (with MFC-experience). This one changes too often to be included in the official Python distro. But the changes are also beneficial. If you have a C++ background, then this one should be extremely easy to pick up. I use it in all my GUI apps now. From what I've read and seen, wxPython uses the native widgets on whatever platform it is deployed on, so it should have the native look and feel most of the time. PyGtk seems to be a modern, very clean and nice approach, but with poor W32-support. Is PyGtk a mature library with respect to version stability and documentation. PyQt is a huge library (thanks to Qt), but not free on W32, or? Is there any possibility that any of the above-mentioned libraries will be included as a standard library in any of the near-future Python distributions? Tkinter is already included with Python and has been for quite some time. I myself program on W32 at work, but use Linux at home. So, which one should I start with in order to reduce the effort of learning something new and to be productive in the shortest time possible? By the way, how do I most easily include plotting capabilities to my Python-apps? The people on the wxPython user's group usually mention matplot for this sort of thing. I think they combine it with wxPython's drawing/ blitting capabilities, but since I don't do that myself, I am not completely sure of the implementation. Carl Hope that helps some!

Cheers, John Sorry...I didn't know about translation tables or I would have mentioned that instead. My bad. Mike -- http://mail.python.org/mailman/listinfo/python-list

I don't know the Unix command for this, but I would just redirect the
output to a file on your system. See the following for more info:
http://www.faqs.org/docs/diveintopython/kgp_stdio.html
You could send the output to a variable and create a file-like stream
too. Either way, read the file (or stream) and then for each line,
split it on the space.
Then you can do the compare and use the email module to email you the
result should it go over your specified amount.
By the by, if you're using Python 2.4 or above, you should switch to
using the subprocess module rather than using os.system since the
latter is being deprecated.

I found the author to be slightly arrogant as he would dismiss certain features of Python on occasion and there were a couple of huh!? moments where he contradicted what seems (to me) to be common Python idioms. But there's a lot to like too. There's a real app or two at the end and it covers using cgi in Python better than any of the other Python books I've read.

This person is a long-term Linux/C/Python programmer, but he claims that the install, config, and library models for C# have proved to be less problematic than Python. So both his courses (intro, data structs, algorithms) are taught in C#. I am a low-end (3-year) journeyman Pythonista, and I was attracted to the language because of its simplicity. And I have come to enjoy the richness of available libraries. Many of the good people of this NG may be 'too close' to answer, but has Python, as a general devel platform, lost its simplicity ? Is library install too complex and unreliable ? Will my dog go to heaven ? If this professor was only using Windows for his environment, then I might be able to understand his argument better. There are many more external modules for Python that don't have Windows installers than there are with binaries. And I've had more than my fair share of broken setup.py files. On the other hand, if all that is needed are the standard libraries, than it's a breeze to install Python since they're all included. Mike These modules exist, but aren't that common. Certainly anything you're likely to be using in an introductory compsci course is well packaged. And even if it's not, it's really not that hard to create packages or installers - a days work of course prep would take care of the potential problem. I stand corrected. Thanks for the clarification. Mike -- http://mail.python.org/mailman/listinfo/python-list

I'm not sure, but I don't think you can bind the a key to a
canvas...you'd want to bind to the rectangle itself somehow.
Some articles on binding:
http://effbot.org/pyfaq/i-can-t-get-key-bindings-to-work-in-tkinter-why.htm
http://www.pythonware.com/library/tkinter/introduction/events-and-bindings.htm
http://docs.huihoo.com/tkinter/an-introduction-to-tkinter-1997/intro06.htm
Info on the Canvas object:
# this one talks about setting the focus on an item within the canvas
so that it has key bindings...maybe that will work.
http://effbot.org/tkinterbook/canvas.htm

I am not a Tkinter expert. I am much better with wxPython, but I am
only starting to be able to answer questions on that topic.
Hopefully someone with more knowledge will show up shortly.

I just found them somewhere in the internet but I can't find them now that I need it. Does someone knows this? Thanks I'm not sure what you're referring to. The best known one is ReportLabs for generating PDFs in Python code. There's also pyPdf for merging PDFs and/or extracting information from them, among other things. http://pybrary.net/pyPdf/ www.reportlab.org Maybe if one of these was listed on a foreign site, it was spelled with a 'Q'?
