python、turtle贪吃蛇重生代码

以下是Python中使用turtle库实现贪吃蛇游戏的示例代码：

import turtle
import random
import time

# 设置游戏窗口
win = turtle.Screen()
win.title("贪吃蛇")
win.bgcolor("black")
win.setup(width=600, height=600)

# 定义蛇头和食物
head = turtle.Turtle()
head.shape("square")
head.color("white")
head.penup()
head.goto(0, 0)
head.direction = "stop"

food = turtle.Turtle()
food.shape("circle")
food.color("red")
food.penup()
food.goto(random.randint(-290, 290), random.randint(-290, 290))

# 定义蛇的身体列表
body = []

# 定义蛇移动的函数
def move():
    # 移动蛇的身体
    for i in range(len(body) - 1, 0, -1):
        body[i].goto(body[i - 1].xcor(), body[i - 1].ycor())

    # 移动蛇头
    if head.direction == "up":
        head.sety(head.ycor() + 20)
    elif head.direction == "down":
        head.sety(head.ycor() - 20)
    elif head.direction == "left":
        head.setx(head.xcor() - 20)
    elif head.direction == "right":
        head.setx(head.xcor() + 20)

    # 检测蛇头是否与食物碰撞
    if head.distance(food) < 20:
        # 食物移动到随机位置
        food.goto(random.randint(-290, 290), random.randint(-290, 290))

        # 添加一个新的身体方块
        new_body = turtle.Turtle()
        new_body.shape("square")
        new_body.color("green")
        new_body.penup()
        body.append(new_body)

    # 检测蛇头是否与边界碰撞
    if head.xcor() > 290 or head.xcor() < -290 or head.ycor() > 290 or head.ycor() < -290:
        time.sleep(1)
        head.goto(0, 0)
        head.direction = "stop"

        # 移除蛇的身体方块
        for b in body:
            b.goto(1000, 1000)
        body.clear()

    # 检测蛇头是否与身体碰撞
    for b in body:
        if head.distance(b) < 20:
            time.sleep(1)
            head.goto(0, 0)
            head.direction = "stop"

            # 移除蛇的身体方块
            for b in body:
                b.goto(1000, 1000)
            body.clear()

    # 延迟移动蛇
    time.sleep(0.1)

    # 循环调用移动函数
    win.ontimer(move, 100)

# 定义蛇头移动的函数
def go_up():
    if head.direction != "down":
        head.direction = "up"

def go_down():
    if head.direction != "up":
        head.direction = "down"

def go_left():
    if head.direction != "right":
        head.direction = "left"

def go_right():
    if head.direction != "left":
        head.direction = "right"

# 绑定键盘事件
win.listen()
win.onkeypress(go_up, "Up")
win.onkeypress(go_down, "Down")
win.onkeypress(go_left, "Left")
win.onkeypress(go_right, "Right")

# 循环调用移动函数
move()

# 主循环
win.mainloop()

希望这个示例可以帮助你重新实现贪吃蛇游戏！
