Refine this to:
def main():
print "hi"
if __name__ == "__main__":
main()
The advantage of the 'if __name__ ..' statement is that you can import the
script without running the 'main' code, e.g. from your unittest module.
Wrapping the main code in a function allows you to call this function from
your unittests and test it like any other function.
Additionally I do usually add an 'argv' argument to main() which I use
instead of sys.argv, so I can easily test it with different arguments.
