What makes you think it doesn't work?
The first pruint is near the start of your code, the last near the end.
So your program appears to have run.

What else were you expecting to see happen?
What is different when you run it from "Python command line"?

In practice there should be no difference between you typing

C:\Python26>shp2png.py C:\\ .png

and typing


C:\Python26> python shp2png.py C:\\ .png

Or are you doing something at the Python >>> prompt?
If so what? How are you "running" it when it works?
