If you want this to execute upon declaring an instance of Starter, rename
this as __init__.

Try this instead:  f = open(os.path.combine('/Users/lguerrasio/myfold',
'initfile.py'),'r')

           f = open("initfile.py",'r')

If you had renamed the function __init__ above, all you would have to do is:

instance_of_starter = Starter(48)

Which makes more sense IMO.

Good luck!
