We will have our first quiz at the end of class Saturday. This means that the Saturday class will not have much time to talk about Python before taking a quiz about it. (But that will be the case every week!) Be sure you read the Python tutorials listed in the assignment and the notes on the course CSNS page. Also, be sure you work on the programming exercises. We will talk about them in class. To jump-start the discussion, I've posted some solutions. (It's a Python notebook, which runs on Jupyter.) Even if you are not able to come up with solutions yourself, which you should try to do first, you should take time to understand the posted solutions -- and be able to explain how they work.
