# Why not to just put all your code under if __name__ == '__main__':
# (AKA why you should use a main(argv) function)
import sys

print param
# You'd think this would fail, but it works, because new_param is in the
# parent level scope. It will fail if you import this file and call
# my_func, of course.
print new_param

# I am adding a new param, so let's unpack it into a new variable
(param, new_param) = sys.argv[1:2]
# Here, I should call my func with this exciting new parameter,
# but I forgot
