Bioinformatics python capstone lesson

This lesson is intended to be a 1.5 hour demo that will sit at the end of a novice python bootcamp and show learners how to apply some of their new skills to bioinformatics. Currently work in progress, contributions/suggestions very welcome!
Really cool lesson! Good work!
Not sure if this is the intended end - but a biologically motivated wrap-up would be great. And maybe a p-value from the script?
