给我一个贪吃蛇的Python代码

当然可以，以下是一个基本的贪吃蛇游戏的 Python 代码：

import turtle
import time
import random

delay = 0.1

# 设置窗口
win = turtle.Screen()
win.title("贪吃蛇")
win.bgcolor("green")
win.setup(width=600, height=600)

# 创建蛇头
head = turtle.Turtle()
head.speed(0)
head.shape("square")
head.color("black")
head.penup()
head.goto(0, 0)
head.direction = "stop"

# 创建食物
food = turtle.Turtle()
food.speed(0)
food.shape("circle")
food.color("red")
food.penup()
food.goto(0, 100)

# 蛇移动的函数
def move():
    if head.direction == "up":
        y = head.ycor()
        head.sety(y + 20)

    if head.direction == "down":
        y = head.ycor()
        head.sety(y - 20)

    if head.direction == "right":
        x = head.xcor()
        head.setx(x + 20)

    if head.direction == "left":
        x = head.xcor()
        head.setx(x - 20)

# 蛇头移动方向的函数
def go_up():
    if head.direction != "down":
        head.direction = "up"

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

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

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

# 设置键盘监听
win.listen()
win.onkeypress(go_up, "Up")
win.onkeypress(go_down, "Down")
win.onkeypress(go_right, "Right")
win.onkeypress(go_left, "Left")

# 游戏循环
while True:
    win.update()

    # 判断蛇头和食物是否接触
    if head.distance(food) < 20:
        x = random.randint(-290, 290)
        y = random.randint(-290, 290)
        food.goto(x, y)

    # 蛇的身体部分跟随蛇头移动
    for index in range(len(body)-1, 0, -1):
        x = body[index-1].xcor()
        y = body[index-1].ycor()
        body[index].goto(x, y)

    if len(body) > 0:
        x = head.xcor()
        y = head.ycor()
        body[0].goto(x, y)

    move()

    # 判断蛇头是否撞墙或自己
    for b in body:
        if b.distance(head) < 20:
            time.sleep(1)
            head.goto(0, 0)
            head.direction = "stop"

            # 清空身体部分
            for b in body:
                b.goto(1000, 1000)

            # 清空身体列表
            body.clear()

    # 添加身体部分
    if len(body) < 1:
        new_body = turtle.Turtle()
        new_body.speed(0)
        new_body.shape("square")
        new_body.color("grey")
        new_body.penup()
        body.append(new_body)

    time.sleep(delay)

# 关闭窗口
win.mainloop()

注意：这只是一个基本的贪
