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

This is good practice. First, it clearly marks your module entry point (assuming you don't have any other executable code at toplevel - yuck). Second, it makes your module importable by other modules without executing, which some tools like code checkers, packagers etc. need to do.
