As this is really a tutor question, I'm cutting the extra parts and
re-posting the meat to the Tutor list (list mom's prerogative):

(And yes, I'd rather responses went to the list; others are struggling
with the same kinds of things and NOT posting...)

In calling a function, you can pass one or more parameters to it. Unlike
may other languages, you can also return multiple parameters.

def readFile(fname):
	... do some stuff...
	hw_type = (something from the file)
	hw_info = (something else from the file)
	return hw_type, hw_info

def main():
	hw_type, hw_info = readFile("foo")

There's also more complex structures; see:
