Hi Keith,
It depends on what you want to do with Python in the end (by the

Here are some of my suggestions (based on current topics and

2. Write a program which determines
Hi Keith,
As a follow-up: I'm sure others might have mentioned this, but I
also recommend doing exercises presented in the book or reference
you're using to learn Python.
