Python TKinter：如何设置子窗口（顶级）的窗口图标

我试图在TKinter内置的主窗口的子窗口中添加一个窗口图标。为了便于移植（也就是说没有丢失的文件），我将base64编码的gif设置为一个变量。我无法为子窗口复制此内容

from Tkinter import *

我想我会和大家分享如何在不使用类的情况下做类似的事情。在我的示例中，我使用了父项和子项来引用窗口，并在窗口上使用不同的背景色来显示在哪里发生的情况，并且我向与图标相关的部分添加了注释

parent = Tk()
parent.title("PARENT")
parent.geometry("200x200")
parent.config(bg="yellow")
