用python turtle库写一个贪吃蛇代码

好的，以下是一个简单的贪吃蛇代码，使用了Python的turtle库：

import turtle
import random

# 设置窗口大小和背景颜色
turtle.setup(500, 500)
turtle.bgcolor("black")

# 创建蛇头
head = turtle.Turtle()
head.shape("square")
head.color("white")
head.penup()
head.goto(0, 0)

# 创建食物
food = turtle.Turtle()
food.shape("circle")
food.color("red")
food.penup()
food.goto(random.randint(-200, 200), random.randint(-200, 200))

# 定义蛇的移动函数
def move():
    head.forward(20)
    if head.distance(food) < 15:
        food.goto(random.randint(-200, 200), random.randint(-200, 200))

    # 检查是否撞墙
    if head.xcor() > 250 or head.xcor() < -250 or head.ycor() > 250 or head.ycor() < -250:
        print("Game Over!")
        turtle.bye()

    # 检查是否撞到自己
    for segment in segments:
        if segment.distance(head) < 20:
            print("Game Over!")
            turtle.bye()

    # 移动蛇的身体
    segments = []
    segments.append(head.clone())
    for i in range(len(segments) - 1, 0, -1):
        x = segments[i - 1].xcor()
        y = segments[i - 1].ycor()
        segments[i].goto(x, y)
    head.color("white")
    head.shape("square")
    head.stamp()
    head.color("green")

    # 设置定时器
    turtle.ontimer(move, 100)

# 开始游戏
move()
turtle.done()

希望这个代码能够帮助你！
