python 贪吃蛇小游戏

以下是使用Python编写的贪吃蛇小游戏的示例代码：

import pygame
import time

# 初始化pygame
pygame.init()

# 设置游戏窗口的宽度和高度
window_width = 800
window_height = 600

# 创建游戏窗口
screen = pygame.display.set_mode((window_width, window_height))
pygame.display.set_caption("贪吃蛇小游戏")

# 定义颜色
white = (255, 255, 255)
black = (0, 0, 0)
red = (255, 0, 0)
green = (0, 255, 0)

# 定义蛇的初始位置和大小
snake_x = 50
snake_y = 50
snake_size = 10

# 定义蛇的移动速度
snake_speed = 15

# 定义蛇的移动方向
snake_direction = "right"

# 游戏主循环
game_over = False
while not game_over    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_over = True

        # 监听键盘事件，控制蛇的移动方向        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                snake_direction = "left"
            elif event.key == pygame.K_RIGHT:
                snake_direction = "right"
            elif event.key == pygame.K_UP:
                snake_direction = "up"
            elif event.key == pygame.K_DOWN:
                snake_direction = "down"

    # 根据蛇的移动方向更新蛇的位置
    if snake_direction == "left":
        snake_x -= snake_speed
    elif snake_direction == "right":
        snake_x += snake_speed
    elif snake_direction == "up":
        snake_y -= snake_speed
    elif snake_direction == "down":
        snake_y += snake_speed

    # 清空屏幕
    screen.fill(black)

    # 绘制蛇的身体
    pygame.draw.rect(screen, green, [snake_x, snake_y, snake_size, snake_size])

    # 更新屏幕显示
    pygame.display.update()

    # 控制游戏帧率
    pygame.time.Clock().tick(30)

# 退出游戏
pygame.quit()
