Help with __name__ == '__main__'

[Erlend J. Leiknes]

if __name__ == '__main__': is a method to avoid the code to be executed if
its imported as a module.

You could simply just remove the """ if __name__ == '__main__': """, but
then you cannot use your code as a module without adding it back (unless you
want it to be executed upon import.
