Intro to Programming and Data Science (Summer 2021)/Day 7 Coding Challenges

There are 7 exercises in today's notebook. I'm assigning the first 5:


 * Exercise 1: Tamara
 * Exercise 2: Zhaozhe
 * Exercise 3: Naomi
 * Exercise 4: Carly
 * Exercise 5: Yihan

The last two exercises are much more open-ended, and I would love to see the variety of what you come up with. The following people are assigned to upload their answers, but I would invite everyone to upload their code + their visualization to Piazza, so that we can all admire your work.


 * Exercise 6: Tiwalade, Jessie, Vanessa
 * Exercise 7: Ji-young, Nate
