You do realize that 

foo = 5 # define at the module level

if __name__ == '__main__':
    bar = 6 # also at the module level

if True:
    ham = 8 # still at the module level

def func()
    # scope has changed, only at the func level
    jam = 9

Nothing magic about if __name__ == '__main__'

Cheers,
