There will only be one default Tk object, but there can be multiple Tk
objects.
import tkinter as tk
f0 = tk.Frame()
This causes creation of a default root
root0 = tk.Tk()
This creates another, hence two different objects.
f0.master
<tkinter.Tk object at 0x015AB6F0>
root0
<tkinter.Tk object at 0x015ABE50>
import tkinter as tk
root0 = tk.Tk()
This creates a root that is set as the default because there was not one
already.
f0 = tk.Frame()
The uses the default root which is root0, hence 1 object.

root0
