How to write the example code of realizing ball evasion with Pygame

Pygame implementation of ball avoidance example code how to write, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

Foreword:

In the Python class this semester, there is really a lot to write code.

Experiment 1 of the course is a backgammon, but the code is sent.

As for the quality of the code, I changed it directly according to the structure divided by myself.

Complain here (the code really sent out is terrible)

I changed it for almost 4 hours and then I don't want to add any more functions.

Write it yourself this time. Then write something like that.

Structural division

I divided it into

Run entrance

Setting Settin

Main master logic

Utils warehouse

In fact, what I want to do is to set it all on the page, but be lazy ~ (I'm going to get a grade point at the end of the term)

Start posting code directly.
