tkinter：如何在窗口之间“naviguate”

Question

在这个新窗口中，我找不到一种方法来确保打印标签，或者实际播放游戏是在my_window中完成的？？

在下面的代码中，我用函数launch_the_game中的标签(label(my_window,text=“game_num value”+str(game_num)).grid（行=5,列=0）来模拟它。这个标签是在root中打印的，而不是在my_window中打印的，这是怎么回事呢？

我不是在叫窗户吗？还是创造他们对吗？谢谢你

from tkinter import *

def launch_the_game():
        global my_window
        global game_num

        Label(my_window, text = "game_num value"  + str(game_num)).pack()
        
def open_new_window(game_num,game_name, dimensions, game_rule):
    global my_window

    my_window = Toplevel()
    my_window.title(game_name)
    my_window.geometry(dimensions)
    Label(my_window, text = "" + game_rule).grid( row = 3, column = 0)
    Button(my_window, text = "LAUNCH " + game_name, command= launch_the_game ) .grid( row = 4, column = 0) 


def assign_game(value):

    global game_name
    global dimensions
    global game_rule
    global game_num
    global my_window
    
    game_num = value

    if value  == 1:
        game_name  = "Guess my number"
        dimensions = "400x600"
        game_rule = " guess a number between 0 and 100"
        game_num = str(value)

    my_window=open_new_window(game_num,game_name, dimensions, game_rule)

    
def my_click_name_UI():

    btn1 = Button(root, text="Guess my number", command= lambda *args: assign_game(1)).pack()
    btn2 = Button(root, text="Guess my name", command= lambda *args: assign_game(2)).pack()

        
root = Tk(className =' Best game ever ! ')
root.geometry("450x150")
root.configure(bg="light blue")
btn3 = Button(root, text="Go play the games!", command=my_click_name_UI)
btn3.pack()

mainloop()

我的朋友发现了问题。我正在分配my_window=open_new_window....返回“blank”，而blank可能是=root。2种固定方法。一个是

        game_name  = "Guess my number"
        dimensions = "400x600"
        game_rule = " guess a number between 0 and 100"
        game_num = str(value)

  open_new_window(game_num,game_name, dimensions, game_rule)

或

    global my_window

    my_window = Toplevel()
    my_window.title(game_name)
    my_window.geometry(dimensions)
    Label(my_window, text = "" + game_rule).grid( row = 3, column = 0)
    Button(my_window, text = "LAUNCH " + game_name, command= launch_the_game ) .grid( row = 4, column = 0) 
    return my_window

这两种情况下都是有效的。他还告诉我开始学习什么是类，并正确地编写代码，以便于阅读；）
