Question

所以在我的程序中，每当我放置grid_remove()函数时，它通常会删除小部件。每当我第一次运行程序时（也就是说，通过错误猜测不会丢失任何点），它会删除大多数小部件。然而，每当我猜错并获得分数（工作正常）时，窗口小部件就会懒洋洋地留在窗口上。有什么帮助吗？

以下是代码:(我认为错误发生在def numright和def wordguess之后的某处

import random
from tkinter import *
from tkinter import messagebox

text_doc = open("test.txt", "r")
text = text_doc.read()
numbOfletters = len(text)
random_letter = random.randint(0,numbOfletters-1)
letter = text[random_letter]
points = 50
username = ""
is_there = 0

你的问题是行（在numright方法的else子句中）：

        self.numright = Label(self, text="That word has {} secret letters".format(is_there))
        self.numright.grid(row=2, column=0)

self.numright是GUIFramework类中的一个方法，您可以在此处踩踏并将其重新分配给Label字段。此外，您可能必须将self.ok按钮放回页面，因为您将grid_removed放在上面。我添加了以下几行：

self.ok = Button(self, text="OK", command = self.numright)
self.ok.grid(row=1, column=8)

到numright方法的末尾，将OK按钮放回原位。然后，我通过制作一个名为self.numright的不同方法来解决问题，这就是我如何发现重新分配的错误。
