用python 写一个 贪吃蛇的游戏

下面是一个简单的 Python 贪吃蛇游戏的示例代码：

import turtle
import time

# 设置窗口大小和标题
turtle.setup(width=600, height=600)
turtle.title("贪吃蛇游戏")

# 设置蛇的初始位置和大小
snake = turtle.Turtle()
snake.shape("square")
snake.color("green")
snake.penup()
snake.goto(0,0)
snake.direction = "stop"

# 设置食物的初始位置和大小
food = turtle.Turtle()
food.shape("circle")
food.color("red")
food.penup()
food.goto(100,100)

# 定义移动函数
def move():
    if snake.direction == "up":
        y = snake.ycor()
        snake.sety(y + 20)
    if snake.direction == "down":
        y = snake.ycor()
        snake.sety(y - 20)
    if snake.direction == "left":
        x = snake.xcor()
        snake.setx(x - 20)
    if snake.direction == "right":
        x = snake.xcor()
        snake.setx(x + 20)

# 定义按键处理函数
def go_up():
    snake.direction = "up"

def go_down():
    snake.direction = "down"

def go_left():
    snake.direction = "left"

def go_right():
    snake.direction = "right"

# 绑定按键
turtle.listen()
turtle.onkey(go_up, "Up")
turtle.onkey(go_down, "Down")
turtle.onkey(go_left, "Left")
turtle.onkey(go_right, "Right")

# 游戏主循环
while True:
    turtle.update()
    # 判断是否吃到食物
    if snake.distance(food) < 20:
        x = turtle.xcor()
        y = turtle.ycor()
        food.goto(x + 20, y + 20)
    move()
    time.sleep(0.1)

这只是一个简单的游戏示例，可能需要进一步添加游戏规则和功能。

这个代码依赖于 turtle 库，在使用之
