It returns a string, not a number. If you don't give your widgets your
own names, Tkinter simply uses the decimal representation of the id of
the Python object associated with the Tk-widget:

>>> from Tkinter import *
>>> top = Tk()
>>> f = Frame(top)
>>> f.pack()
>>> str(f)
'.135839768'
>>> label = Label(f, text="Tkinter")
>>> label.pack()
>>> str(label)
'.135839768.135839840'

What exactly do you mean by 'python name'?

What you get sith str is the name that is used by tk internally. It's
unique and you should be able to automatically build a dictionary
mapping these names to the help-text or whatever information you need.
