Python program start

Question

Should I start a Python program with:

if__name__ == \'__main__\':
some code...

And if so, why? I saw it many times but don\'t have a clue about

Answer 1

A better pattern is this:

def main():
   ...

if __name__ == '__main__':
   main()

This allows your code to be invoked by someone who imported it, while also making programs such as pychecker and pylint work.
