在其中一个视图中，有一个用于关闭实际视图的按钮，它可以工作，但当我再次尝试打开该视图时，它会显示下一个错误：Exception in Tkinter callback

Traceback (most recent call last):

File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 1545, in __call__

return self.func(*args)

TclError: bad window path name ".140687059771120.140687059776216.140687059776504.140687059776576"

销毁窗口的功能是：def close_windows(self):

"This function destroys the window"

self.master.destroy()

这是视图：import Tkinter as tk

class Lockers:

lockerList = ["1", "2", "3", "4", "5"]

buttonsList = []

def __init__(self, master):

self.master = master

self.frame = tk.Frame(self.master)

self.master.minsize(width = 250, height = 200)

self.initialize_lockers()

self.frame.grid()

tk.Label(self.frame, text = "Seleccione el locker que desea revisar:").grid(row = 0, columnspan = 4)

i = 0

while i < len(self.lockerList):

self.buttonsList[i].grid(columnspan = 4) #HERE THE ERROR

i += 1

tk.Label(self.frame, text = "").grid(columnspan = 4)

self.quitButton = tk.Button(self.frame, text = 'Salir', width = 8, command = self.close_windows)

self.quitButton.grid(column = 1, columnspan = 2)

函数initialize_lockers()将一些按钮追加到buttonsList。

在阅读了一段时间之后，我发现在执行destroy()并尝试网格化某些内容之后，它将显示一个错误，但我不明白为什么。
