One solution is outlined here:

This is useful for the development machine. It keeps the DOS window
open, and leaves you in the Python debugger, where you can play around
even more to find out about the state of your program.

For py2exe-packages apps you should redirect sys.stdout and sys.stderr
into a log-file.
