使用海龟的贪吃蛇游戏 (Python)

Question

所以我一直在做我的项目，就是在 Python 中制作贪吃蛇游戏，我的蛇基本上吃圆形食物，它也可以穿过墙壁它玩起来更容易，我想我可能打错了东西或者可能是版本问题。我也看过很多 Youtube 视频，但没有得到任何帮助。谁能告诉我我在下面的代码中犯的错误？

Python 使用 Turtle 的贪吃蛇游戏

s.bgcolor("black")
s.setup(width=600, height=600)

s.tracer(0)

head.speed(0)
head.shape("square")
head.color("white")
head.fillcolor("red")
head.goto(0,0)
head.penup()
head.direction="stop"

food=turtle.Turtle()
food.speed(0)
food.shape("circle")
food.color("white")
food.fillcolor("yellow")
food.penup()
food.ht()
food.goto(0,150)
food.st()

让你的游戏无法运行（吃东西）的是这两行：

x=random.randint(290,-290)
y=random.randint(290,-290)

参数需要反过来：

x=random.randint(-290, 290)
y=random.randint(-290, 290)
