python贪吃蛇代码

以下是一个简单的Python贪吃蛇代码示例，可以在命令行中运行：

import curses
import random

# 初始化窗口
s = curses.initscr()
curses.curs_set(0)
sh, sw = s.getmaxyx()
w = curses.newwin(sh, sw, 0, 0)
w.keypad(1)
w.timeout(100)

# 初始化蛇和食物
snk_x = sw//4
snk_y = sh//2
snake = [
    [snk_y, snk_x],
    [snk_y, snk_x-1],
    [snk_y, snk_x-2]
]

food = [sh//2, sw//2]
w.addch(food[0], food[1], curses.ACS_PI)

# 初始化分数
score = 0

# 定义移动方向
key = curses.KEY_RIGHT

# 开始游戏循环
while True:
    next_key = w.getch()
    key = key if next_key == -1 else next_key

    # 判断游戏结束
    if snake[0][0] in [0, sh] or snake[0][1] in [0, sw] or snake[0] in snake[1:]:
        curses.endwin()
        quit()

    # 计算新的蛇头位置
    new_head = [snake[0][0], snake[0][1]]
    if key == curses.KEY_DOWN:
        new_head[0] += 1
    if key == curses.KEY_UP:
        new_head[0] -= 1
    if key == curses.KEY_LEFT:
        new_head[1] -= 1
    if key == curses.KEY_RIGHT:
        new_head[1] += 1

    # 添加新的蛇头
    snake.insert(0, new_head)

    # 判断是否吃到食物
    if snake[0] == food:
        food = None
        while food is None:
            nf = [
                random.randint(1, sh-1),
                random.randint(1, sw-1)
            ]
            food = nf if nf not in snake else None
        w.addch(food[0], food[1], curses.ACS_PI)
        score += 1
    else:
        tail = snake.pop()
        w.addch(tail[0], tail[1], ' ')

    w.addch(snake[0][0], snake[0][1], curses.ACS_CKBOARD)

    # 显示分数
    w.addstr(0, 2, 'Score: ' + str(score))

这个代码使用了 `curses` 模块来控制命令行界面，实现了一个简单的贪吃蛇游戏。
