大家来看看我的代码有什么问题？画布窗口老闪退

gamebase.py文件

from turtle import *

def square(x,y,size,color_name): up() goto(x,y) down() color(color_name) begin_fill()

forward(size)
left(90)
forward(size)
left(90)
forward(size)
left(90)
forward(size)
left(90)

end_fill()

snake.py文件

from turtle import * from gamebase import square from random import randrange

snake=[[0,0],[10,0],[20,0],[30,0],[40.0],[50,0]] apple_x=randrange(-200,200) apple_y=randrange(-200,200)

def gameLoop(): global apple_x,apple_y

for n in range(len(snake)):
    square(snake[n][0],snake[n][1],10,"black")


square(apple_x,apple_y,10,"red")
update()

setup(420,420,0,0) hideturtle() tracer(False) gameLoop() done()

兄弟们就是这个了，我看终端他说列表索引超出范围？什么东东？ 这个写作器好奇怪
