python初学，贪吃蛇完整代码记录

跟着B站up主做的，权当是仓库记录一下，效果直接粘贴跑下就好了

import turtle
from random import randrange
snake = [[0,0],[0,10],[0,20]]
aim = [0,10]
food = [-10,0]

def change_direction(x,y):
    aim[0] = x
    aim[1] = y

def square(x,y,size,color):
    turtle.penup()
    turtle.goto(x,y)
    turtle.pendown()
    turtle.color(color)
    turtle.begin_fill()
    for i in range(4):
        turtle.forward(size)
        turtle.left(90)
        turtle.end_fill()
def inside(head):
    return -250
