The following is a simple Python snake game code:

Snake game competition in github, learning path
1. Learn the basics of Python language, including syntax, data types, control structures, functions, modules, etc.

2. Learn the Pygame game development framework and understand its basic concepts, API interfaces and usage methods.

3. Study the rules and gameplay of the Snake game, and understand the logic and implementation of the game.

4. Read the existing Snake game code and understand its implementation ideas and code structure.

5. Improve and optimize the Snake game based on your own understanding and needs, such as increasing difficulty, adding new features, beautifying the interface, etc.

6. Participate in the Snake Game Competition, communicate, learn and compete with other developers to improve your programming level and game development capabilities.

8. Continue to learn and practice, continuously improve your programming skills and game development experience, and prepare for future projects and competitions.

This code uses the pygame library to implement a simple snake game, including functions such as snake movement, food generation, score calculation, and game end judgment. You can modify and extend it according to your needs.
