You are correct...but I think that's pretty common across GUI
toolkits. The GUI has it's own main loop that will get blocked if
another thread tries to do something or you'll end up with strange
behavior. As far as I know, each toolkit has its own methods for
working around this. In wxPython's case, you can use wx.CallAfter,
wx.CallLater and several others to manipulate the GUI from a thread.
There's some other ways of going about this on the wxPython wiki:

As you will find, there are various methods within wxPython that are
threadsafe (such as wx.CallAfter) and you can use those to communicate
with and update your GUI. From what I've read, this is normal across
GUI toolkits. They all have special ways to work with threads.
In the future, I highly recommend that you join and post to the
wxPython list as that's where you'll get the best targeted advice (see
their website). This list is great for general questions though.

wxPython's next release as there are some goofy things going on with
the manifest files. Maybe this doesn't affect Linux users
though...however, if you experience weird issues, that may be the

This is the preferred method...there is a slight caveat that when you
actually want to close the dialog, you'll need to use the dialog's
Destroy() method...

I'd like to ship only the .pyc files for a module. I was hoping the
standard distutils setup.py could handle this, but so far, I've not
figured out how.
After a bit of work, I discovered that if I create a MANIFEST.in file,
and put 'include mymodule/*.pyc' and 'exclude mymodule/*.py' in it,
then
quot;EssentialPDF")
# now EssentialPDF should be in your python namespace
# so you can do something like this:
from EssentialPDF import SomeModule
# or
EssentialPDF.SomeModule
At least, that's how it seems to work for most .NET libraries. Hope
that helps.

Well, I'm an idiot. Obviously, the line "VALUES (%s, %s, %s);" needs
to be modified to adapt for the number of arguments in the list. But
otherwise

Hello all, I have a question about the if/else aspect of list comprehension:
I would like to go through a list and place quotes around an item if
it is a string, and keep the item the same if it's anything else:
e.g.['a',9,'8b'] --> ['"a"', 9, '"8b"']
I understand that if/else list comprehension
en you'll have to
change it slightly of course, probably by using a nested loop.
Hopefully this isn't a homework question, but even if it is, it's an
interesting exercise.

Zelle's Python Programming book is pretty good (and was written by a
college professor) and I've heard good things about ORielly's Learning
Python by Lutz.

Hello all,
I'm writing a web app and wanted to do some html generation (I really do not

Google's first hit was this:

It's not a library, but it's the way that Yahoo itself recommends.

This works fine for me on Windows XP and Python 2.5. It looks like
Rebecca is using Python 2.2, which might be the issue. I would also
upgrade to the latest PyWin32 as well. I'm using 212.

If it works that way in IDLE and from the command line python, then
it's almost proof positive that pydev goofed up.
