python 贪吃蛇

好的，以下是一个简单的 Python 贪吃蛇游戏：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 定义窗口大小
window_width = 600
window_height = 400

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

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

# 定义贪吃蛇块的大小和初始位置
block_size = 10
snake_x = window_width / 2
snake_y = window_height / 2

# 定义贪吃蛇移动的初始方向
direction = "right"

# 定义食物的初始位置
food_x = round(random.randrange(0, window_width - block_size) / 10.0) * 10.0
food_y = round(random.randrange(0, window_height - block_size) / 10.0) * 10.0

# 定义贪吃蛇身体的初始长度和坐标列表
snake_length = 1
snake_list = []

# 定义游戏结束的变量
game_over = False

# 定义计分板
font_style = pygame.font.SysFont(None, 30)

def message(msg, color):
    message = font_style.render(msg, True, color)
    screen.blit(message, [window_width / 6, window_height / 3])

# 定义游戏循环
clock = pygame.time.Clock()

while not game_over:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_over = True
        if 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"

    # 移动贪吃蛇
    if direction == "right":
        snake_x += block_size
    elif direction == "left":
        snake_x -= block_size
    elif direction == "up":
        snake_y -= block_size
    elif direction == "down":
        snake_y += block_size

    # 判断是否撞到边界
    if snake_x >= window_width or snake_x < 0 or snake_y >= window_height or snake_y < 0:
        game_over = True

    # 绘制游戏窗口
    screen.fill(white)

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

    # 绘制贪吃蛇身体
    snake_head = []
    snake_head.append(snake_x)
    snake_head.append(snake_y)
    snake_list.append(snake_head)
    if len(snake_list) > snake_length:
        del snake_list[0]

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

    for block in snake_list:
        pygame.draw.rect(screen, black, [block[0], block[1], block_size, block_size])

    # 判断是否吃到食物
    if snake_x == food_x and snake_y == food_y:
        food_x = round(random.randrange(0, window_width - block_size) / 10.0) * 10.0
        food_y = round(random.randrange(0, window_height - block_size) / 10.0) * 10.0
        snake_length += 1

    # 绘制计分板
    score = snake_length - 1
    score_text = font_style.render("Score: " + str(score), True, black)
    screen.blit(score_text, [0, 0])

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

    # 控制游戏速度
    clock.tick(10)

# 关闭 Pygame
pygame.quit()

运行代码后，即可开始游戏。按方向键控制贪吃蛇的移动，吃到食物后贪吃蛇的长度会加一。如果贪吃蛇撞到边界或者碰到自己，则游戏结束。
