Based on UMichigan's coursera Intro to DS with Python course.
Note: Repository only includes source files and solutions for Week 2 to Week 4 assignments since Week 1 was a quiz. You can easily find Week 2-3 solutions online. Week 4 is definitely more difficult for a Py beginner.
I've found reading through other people's work a lot of help. Unfortunately, whatever I found was not helpful, not commented on, or just the answers with little explanation. I wrote my code to be as pandorable as possible, and commented more on the t-test function for Week 4.
Hope this helps!
