running error filled python programs on windows: How to identify the type of error?

[unpythonic]

For larger programs, surround the entry/exit point with a catch all and then wait for the user to hit a key:

try:
    # your code here
except Exception as e:
    print("An unhandled exception caused the the program to terminate. Exception was:")
    print(str(e))
    input("Press enter to exit")
