Question

我正在使用带有Windows的python 3.4.1，当我关闭我的Tkinter时，我获得了一个关于移动tkinter函数的错误消息。该应用程序工作正常，但当我关闭我的应用程序时，shell报告我这个错误消息：

C:\Python34\python.exe "E:/ProgramasPython3/Programas TKinter/JuegoPong/Pong.py"
Traceback (most recent call last):
  File "E:/ProgramasPython3/Programas TKinter/JuegoPong/Pong.py", line 96, in <module>

    pelota.dibujar()

    self.tk.call((self._w, 'move') + args)
_tkinter.TclError: invalid command name ".42952128"

Process finished with exit code 1

这是我的代码：

该应用程序是一个简单的乒乓球游戏。

Pelota是Ball Raqueta是网球拍 dibujar是情节 golpea raqueta是打网球拍

Answer 1

我想你可以找到一个更好的方法但是把它放在一个try / except中会没有任何错误。

     while 1:
        try:
            pelota.dibujar()
            raqueta.dibujar()
            tk.update_idletasks()
            tk.update()
            time.sleep(0.01)
        except Exception as e:
            break
