用Python写一个贪吃蛇

好的，我可以为您提供一个简单的Python贪吃蛇游戏代码。 请注意，这只是一个示例，您可以根据自己的需求对其进行修改：

import turtle
import time

wn = turtle.Screen()
wn.title("贪吃蛇游戏")
wn.bgcolor("green")
wn.setup(width=600, height=600)

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

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

# 增加身体
segments = []

# 移动蛇头
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 == "left":
        x = head.xcor()
        head.setx(x - 20)

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

# 控制方向
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"

# 绑定控制事件
wn.listen()
wn.onkeypress(go_up, "Up")
wn.onkeypress(go_down, "Down")
wn.onkeypress(go_left, "Left")
wn.onkeypress(go_right, "Right")

# 主循环
while True:
    wn.update()

    # 碰到边界
    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"

        # 清除身体
        for segment in
