I always structure this aspect as:
... at or near top of script ...
def main(argv):
... do main logic here ...
... at bottom ...
if __name__ == '__main__':
sys.exit(main(sys.argv))
This has the benefits of (a) putting the main program at the top where it is
easy to see/find and (b) avoiding accidently introduction of dependence on
global variables - because verything is inside main() it has the same behaviour
as any other function.
