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.
