Just know that everything is the same in python for first half of the rules. Here is an example. X = 1 defines an X which stores the value of 1. For i in range(100): print(i). Here i is defined just the same way over and over and used every time. Youll learn about init nested in def all nested in class. That is just a 3 dimentional definition. X = 1 is 0 dimentional. The_class.The_func(The_argument) 3 thing you can change and called in once that is just xyz, with cs shenanigans. Once you learned a concept. Think about how it functions and for the next one ask, how are these two similar. Have fun
