获取错误"No attribute draw"

Question

所以我试图使用图形绘制三个单独的骰子，虽然我终于让它们出现了，但我现在得到了这个错误

>>> Game()
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    Game()
  File "C:UsersBrandonDesktopFinalProject3.py", line 19, in Game
    Green.draw(Gamewindow)
AttributeError: 'DieViewGreen' object has no attribute 'draw'

这对我来说毫无意义，因为图形应该导入它。

我的代码中缺少什么吗？

from graphics import *
class DieViewGreen:
    """ DieView is a widget that displays a graphical representation
    of a standard six-sided die."""

我运行类的函数是这样的，它调用中的dieview类（有三个类似于上面的），并用它来绘制窗口

 from graphics import *
    from DieViewYellow import *
    from DieViewGreen import *
    from DieViewRed import *
    from Button import *
    import random

    def Game():
        """Runs the game"""
        Gamewindow = GraphWin('Game', 200, 200)
        Green = DieViewGreen(Gamewindow, Point(40,75),20)
        Yellow = DieViewYellow(Gamewindow, Point(95,75),20)
        Red = DieViewRed(Gamewindow, Point(150,75),20)
        Green.draw(Gamewindow)
        Roll = Button(Gamewindow, Point(100,130), 160, 20, "Roll Dice")
        Continue = Button(Gamewindow, Point(55,170), 70, 20, "Continue")
        while True:
            pt=Gamewindow.getMouse()
            if roll.clicked(pt):
                DieViewGreen(Gamewindow, Point(40,75),3)
            else:
                continue
            #else:
           #     Exitbutton = "Exit"
           # Stopexit = Button(Gamewindow, Point(145,170), 70, 20, Exitbutton)
          #  Buttons = [Roll, Continue, Stopexit]
           # for i in range(len(Buttons)):
          #      Buttons[i].activate()
          #  n = Gamewindow.getMouse()

Answer 1

该错误的简单含义是您的DieViewGreen类中没有draw函数。您的程序希望有一个。

Answer 2

问题在我的实际游戏代码中，而不是我的die视图中，因为我在不需要的时候使用了Green.draw
