Yes. The variable $? should be bound to the return value of the last

You need to look up the matplotlib.dates package - it's covered briefly in

Hmm, an answer of sorts: Inkscape's Windows build comes with MSVCR70.dll and
MSVCR71.dll (but not MSVCP71.dll). As it's a big and high-profile project

I've written a program in Python using wxPython and Matplotlib and would

distribute and installable version for Windows, but this needs MSVCR71.dll

If you think about building up from the simplest case:
f([]) = []

It doesn't know, but if the program runs for a while without repeating

I suspect I may be missing something vital here, but Python's garbage
collection doesn't seem to work as I expect it to. Here's a small test
program which shows the problem on python 2.4 and 2.5:

Is locking mandatory or co-operative? I don't have any control over the
process which is doing the writing, so if it's co-operative it's no good to
me.
If it's mandatory, th
