Python3 - How do I import a class from another file

For some reason I still aim to keep my (running) programs as small as 
possible - even though the ammount of memory has grown more than a 
thousandfold since I started programming.  Old habits die hard.

Any reason to put the testcode in a procedure instead of just have it 
directly follow the "if __name__ == '__main__' " test ?

Thanks.

:-) If I ever want/need to share my code with others (or post here as part 
of a question) it is a good idea to conform to certain standards to keep it 
easily readable.  It will take some getting acustomed to though, as every 
language seems to have its own way to do it  (I myself prefer single prefix 
chars to indicate the variables intended type).
