your minor issue here is your "or" test, which is not doing what you think
it does.
You're testing here for either of the following to conditions:
1) raw_input != "quit"
2) "q" (Python can't know that you want raw_input != "q" here!!)
Now any non-empty string in Python tests True, so your while loop never stops.
There are two solutions for that:
the obvious: while not (raw_input == "quit" or raw_input == "q")
or the pythonic way: while raw_input not in ("quit", "q")
The second form definitely is preferable over the first when you have to
test for more than two conditions.
For your other questions see Chris' answers.

Best,
Wolfgang
