编写一个贪吃蛇游戏的python代码

编写一个简单的贪吃蛇游戏Python代码需要一些基本的游戏元素，如屏幕、蛇的身体、食物、得分等。下面是一个基础版本的代码框架：

import curses
import random

# 初始化窗口
stdscr = curses.initscr()
curses.curs_set(0)  # 隐藏光标

# 设置窗口大小
win_height, win_width = stdscr.getmaxyx()

# 蛇的位置和方向
snake = [[5, 5], [4, 5], [3, 5]]
direction = 'down'

# 食物位置
food_x, food_y = random.randint(0, win_width - 1), random.randint(0, win_height - 1)

def move_snake():
    new_head = snake[-1]
    if direction == 'up':
        new_head[0] -= 1
    elif direction == 'down':
        new_head[0] += 1
    elif direction == 'left':
        new_head[1] -= 1
    else:
        new_head[1] += 1

    snake.insert(0, new_head)
    if snake[0] == [food_x, food_y]:
        score += 1
        eat_food(food_x, food_y)
    else:
        tail = snake.pop()
        stdscr.addch(tail[0], tail[1], ' ')

def eat_food(x, y):
    global food_x, food_y
    food_x, food_y = random.randint(0, win_width - 1), random.randint(0, win_height - 1)

while True:
    for event in stdscr.getch():  # 检查用户输入
        if event == ord('w') and direction != 'down':
            direction = 'up'
        elif event == ord('s') and direction != 'up':
            direction = 'down'
        elif event == ord('a') and direction != 'right':
            direction = 'left'
        elif event == ord('d') and direction != 'left':
            direction = 'right'

    move_snake()
    stdscr.clear()
    for body_part in snake:
        stdscr.addch(body_part[0], body_part[1], '*')
    stdscr.addstr(0, 0, f"Score: {score}")
    stdscr.addch(food_x, food_y, '@')
    stdscr.refresh()

curses.endwin()  # 关闭窗口

这个代码只是一个非常简化的版本，实际游戏中还需要处理边界检查、碰撞检测以及玩家退出游戏等情况。如果你对游戏开发感兴趣，建议学习更专业的库如pygame或Kivy。
