Python implements Snake [including code and explanation]

Python implements Snake: Create your own classic game

In program development, some simple and interesting games are the most popular. Among them, the Snake game is a classic and popular mini-game that many people like to play. The Python language can help us easily implement the Snake game. This article will introduce how to use the Python language to implement this small game.

First, let us understand the rules of the snake game: players need to control a snake to eat food. The length of each piece of food eaten increases by one. When the snake's head touches its own body or touches the boundary, the game ends. We know that snakes are composed of multiple blocks. Each snake has a head and several body segments. The snake can change its direction and position by moving.

Next, we will use the Pygame library to implement the Snake game. Pygame is a cross-platform game development framework in Python that can help us create 2D games quickly and easily.

The following is the code implementation:

import pygame
import random

# 定义常量
WINDOW_WIDTH = 400
WINDOW_HEIGHT = 400
SNAKE_SIZE = 10
FOOD_SIZE = 10
FPS = 30

# 定义颜色常量
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
RED = (255, 0, 0)
BLUE = (0, 0, 255)

# 初始化 Pygame
pygame.init()

# 设置窗口大小
window = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))

# 设置窗口标题
pygame.display.set_caption('贪吃蛇')

# 设置游戏时钟
clock = pygame.time.Clock()

# 定义蛇和食物的类
class Snake:
    def __init__(self):
