[wxPython-users] sys.path adjusted?

[Jorgen Bodde]

Hi Patrick,

That's what I did now, I am not a python veteran, so you might be
right. However I have not seen sys.path[0] change since I used
wxWidgets. It looked odd that I would have to resort to putting code
at the very beginning of my module to grab sys.path before it gets
changed. But you might be right, if it is an unwritten rule that the
insert should go at the beginning (beats me why) then I will keep this
construction.

Regards,
- Jorgen
