A beginner in python. I hope you can give me more advice on python. I hope you will give me more comments: I wrote them in the comments answered by @ bhuztez. You can send it to the top layer.
Here, the @ blue big answer is a misunderstanding, and
Note: TheMath object is an intrinsic object that you can call all of its properties and methods without having to create it, directly using math as an object. This is the difference between it and the Date,string object.Properties of the Math
