1. Introduction
1.1 Definition
Pygame is a popular Python game development library that provides many features that allow developers to easily create 2D games. It has good cross-platform support and can run on multiple operating systems such as Windows, MacOS, and Linux. In this article, we will introduce the characteristics and usage of the Pygame library to help you understand how to use the Pygame library for game development. It provides many operating modules, such as image module (image), sound module (mixer), input/output (mouse, keyboard, display) module, etc.
