好的，下面是一个简单的基于命令行的Python贪吃蛇游戏示例： ```python import curses from random import randint # 初始化窗口 stdscr = curses.initscr() curses.curs_set(0) sh, sw = stdscr.getmaxyx() w = curses.newwin(sh, sw, 0, 0) w.keypad(1) w.timeout(100) # 设置初始状态 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(int(food[0]), int(food[1]), 'O') key = curses.KEY_RIGHT while True: next_key = w.getch() key = key if next_key == -1 else next_key # 检查是否碰到边界或者自身 if snake[0][0] in [0, sh] or \ snake[0][1] in [0, sw] or \ snake[0] in snake[1:]: curses.endwin() quit() 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 snake.insert(0, new_head) # 吃到食物的情况 if snake[0] == food: food = None while food is None: nf = [ randint(1, sh-1), randint(1, sw-1) ] food = nf if nf not in snake else None w.addch(food[0], food[1], 'O') else: tail = snake.pop() w.addch(int(tail[0]), int(tail[1]), ' ') w.addch(int(snake[0][0]), int(snake[0][1]), '#') ``` 这段代码创建了一个基本版本的“贪吃蛇”游戏，在终端中运行，并利用了`curses`库来进行图形化界面操作。这个游戏里包含了以下几个要素： - 窗口初始化以及键盘控制设置； - 贪吃蛇起始位置及形状设定； - 食物生成规则和碰撞检测机制。
