贪吃蛇 python

好的，以下是一个简单的贪吃蛇游戏的 Python 代码：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 游戏区域的尺寸
width = 800
height = 600

# 创建游戏窗口
screen = pygame.display.set_mode((width, height))

# 设置游戏标题
pygame.display.set_caption("贪吃蛇")

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

# 蛇的初始位置
x = width / 2
y = height / 2

# 蛇的初始移动方向
direction = "right"

# 蛇的初始长度
snake_length = 1

# 蛇身体的坐标列表
snake_list = []

# 生成食物的随机坐标
food_x = round(random.randrange(0, width - 10) / 10.0) * 10.0
food_y = round(random.randrange(0, height - 10) / 10.0) * 10.0

# 游戏循环
game_over = False
while not game_over:

    # 监听游戏事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_over = True
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                direction = "left"
            elif event.key == pygame.K_RIGHT:
                direction = "right"
            elif event.key == pygame.K_UP:
                direction = "up"
            elif event.key == pygame.K_DOWN:
                direction = "down"

    # 根据移动方向更新蛇的坐标
    if direction == "right":
        x += 10
    elif direction == "left":
        x -= 10
    elif direction == "up":
        y -= 10
    elif direction == "down":
        y += 10

    # 清空游戏窗口
    screen.fill(black)

    # 绘制食物
    pygame.draw.rect(screen, green, [food_x, food_y, 10, 10])

    # 绘制蛇
    snake_head = []
    snake_head.append(x)
    snake_head.append(y)
    snake_list.append(snake_head)
    if len(snake_list) > snake_length:
        del snake_list[0]

    for segment in snake_list[:-1]:
        if segment == snake_head:
            game_over = True

    for segment in snake_list:
        pygame.draw.rect(screen, white, [segment[0], segment[1], 10, 10])

    # 如果蛇吃到了食物，长度加一，重新生成食物
    if x == food_x and y == food_y:
        snake_length += 1
        food_x = round(random.randrange(0, width - 10) / 10.0) * 10.0
        food_y = round(random.randrange(0, height - 10) / 10.0) * 10.0

    # 更新游戏窗口
    pygame.display.update()

    # 控制游戏帧率
    clock = pygame.time.Clock()
    clock.tick(15)

# 退出游戏
pygame.quit()
quit()

这个游戏还比较简单，如果你想要实现更复杂的功能，可以参考 Pygame 的文档或者其他网上的教程。
