Lesson 2

Ready for review (I hope)!  Time consuming, but fun and interesting!  Fingers crossed everything is correct!
I really appreciate how you're printing your work here to check it. It's a good habit to start but might become problematic later. Feel free to continue doing so for now but also work to become comfortable using `python -i` to run your code and access the variables from the shell. That will grow in importance as use of `print` diminishes.
