How to change these number(is it a widget ID?) to a meaning name?

The number strings as names are the defaults that came from tkinter, not tcl/tk. In 3.6, the default names were changed to be versions of the class name.

>>> import tkinter as tk
>>> r = tk.Tk()
>>> b = tk.Button(r)
>>> b
<tkinter.Button object .!button>
>>> b2 = tk.Button(r)
>>> b2
<tkinter.Button object .!button2>
