[Tkinter] identify window

[Larz60+]

for master window use withdraw, not destroy.
You will have to capture exit so that you can manually destroy at end
for example, my code add line 11:

import tkinter as tk

class DynamicWindows:
    def __init__(self, parent):
        parent.title('Parent window')
        parent.geometry('300x300+500+500')
        self.startx = 10
        self.starty = 10
        self.all_windows = []
        parent.withdraw()
