Actually it does run it when you import, just not the bit after the
if __name__ = "__main__".
The point of modules is that you don't usually want them to run as a
program, you import them so as to get access to the functions within
them. You want to control when they are called from your own code.
So although Python imports do run the file, normally all that happens is
that a few classes and functions get defined and, possibly, a few global
variables get initialized.
