试图做一个图形骰子辊，我不知道为什么'形状'是未定义的

Question

我试图给它的外观滚动通过使模具出现在屏幕上等待一点，然后取消绘制它，使另一个可以出现。我一直收到一个错误，说“形状”没有定义。刚开始编写代码，所以不要对我太苛刻。你知道吗

        shape.undraw()

我使用的是python3.6.3，请帮助我的编码老师，他似乎不太会编程。你知道吗

for循环中的shape变量不是全局变量，因此需要将其设为全局变量，或者可以将其放入类中：

from graphics import *
win = GraphWin ("Rolling Dice", 200,200)
from random import *
import time

win.yUp
shape = Rectangle(Point(0,0), Point(1,1))

def One():
    global shape
    shape = Rectangle(Point(150,150), Point(60,60))
    shape.draw(win)
    middleDot = Circle(Point(105,105), 8)
    middleDot.setFill('black')
    middleDot.draw(win)


def Two():
    global shape
    shape = Rectangle(Point(150,150), Point(60,60))
    shape.draw(win)
    RightDot = Circle(Point(125,125), 8)
    RightDot.setFill('black')
    RightDot.draw(win)
    LeftDot = Circle(Point(85,85), 8)
    LeftDot.setFill('black')
    LeftDot.draw(win)


def Three():
    global shape
    shape = Rectangle(Point(150,150), Point(60,60))
    shape.draw(win)
    midDot = Circle(Point(105,108), 8)
    midDot.setFill('black')
    midDot.draw(win)
    topDot = Circle(Point(105,80),8)
    topDot.setFill('black')
    topDot.draw(win)
    botDot = Circle(Point(105,135), 8)
