如何解决“标签”在 tkinter 中没有 len() 问题的问题？

Question

import tkinter as tk

window = tk.Tk()
window.title("Player number,rating, and name")
window.minsize(800,800)

lastname = ["Fook", "Bill", "Nine", 
"Chen","Ashley","Noon",'Zen','Naphut',"Cole",'Takeru']
player_number = [1,41,33,3,2,4,5,6,7,8]
rating = [10,1,4,5,6,8,3,4,10,10]

question = tk.Label(master=window, text=
"Type 1, for player's name and rating \nType 2, for players who score 9 or 10"
 + "\nType 3, for players who score 1"
)
question.pack()

input_Box = tk.Entry(master=window)
input_Box.pack()

def menu():
    input_Box_get = int(input_Box.get())

    if input_Box_get == 1:
        def menu1():
            number_input_get = int(number_input.get())
            show = ''
        for i in range(len(player_number)):
            if number_input_get == (player_number[i]):
                show += lastname[i] + ' : ' + rating[i]
                output2.configure(text=show)
    
        player_number = tk.Label(master=window,text='Input player number here in the box:')
        player_number.pack()
    
        number_input = tk.Entry(master=window)
        number_input.pack()

        Button2 = tk.Button(master=window,text='Enter',command=menu1)
        Button2.pack()

        output2 = tk.Label(master=window)
        output2.pack()

    if input_Box_get == 2:
        show = ''
        for i in range(len(rating)):
             if rating[i] == 9 or rating[i] == 10:
                 show += lastname[i] + ','
                 output.configure(text=show)

    if input_Box_get == 3:
        show = ''
        for i in range(len(rating)):
             if rating[i] == 1:
                show += lastname[i] + ','
                output.configure(text=show)

Button1 = tk.Button(master=window, text="Enter", command=menu)
Button1.pack()

output = tk.Label(master=window)
output.pack()

window.mainloop()

在 Vscode 的终端中显示的此代码的 output 是 'Label' has no length() def menu1() 不起作用并且它不会显示在 tkinter GUI 中。 也许问题是 def function 中的 def function 可能不正确。 所以我不知道如何解决这个问题。 有人可以帮忙吗？

我无法重现您所说的内容，但我可以在您的代码中看到其他问题。 您需要将您在 function 中分配的变量定义为全局变量以使其工作。 您必须调用 function 菜单才能将其付诸实施。 而且您还没有定义询问玩家编号的输入框。

在这里，您的代码修复了所有多个提到的问题。 那里似乎仍然存在问题，因此请自行修复剩余问题，因为代码现在运行正常。 在代码本身中查看我在代码中修复的内容的详细信息：
