Dear Dr. Nelson,
Here are some of my personal suggestions about the materials of Python Objects, OOP (Day3-10/7):
For the part of introduction to Classes, I think it might be useful to highlight or emphasize the importance of "self", since for people who are new to object-oriented programming , forgetting to add "self" might be a common but significant problem.
For the part of inheritance, I think it might be helpful to include something about function (method) overriding, overloading and the usage of "super()". Those are included in the reading materials that you have provided but might be ignored easily.
