Summary: digit-only tag values are mishandled in Tkinter
Initial Comment:
It appears that most Tkinter tag operations fail on
digit-only tag values
>>> from Tkinter import *
>>> root=Tk()
>>> c=Canvas(root)
>>> c.create_line(0,0,100,100, tags="123")
1
>>> c.gettags(1)
('123',)
>>> c.pack()
>>> c.find_withtag("123")
()
tkinter docs:
http://www.pythonware.com/library/tkinter/introduction/x2017-concepts.htm
only say this about tag values:
"Tags are ordinary strings, and they can contain
anything except whitespace."
So this behaviour seems like a bug.

This is a documentation bug. The Tk documentation says
(canvas, section "ITEM IDS AND TAGS"):
Each item may also have any number of tags
associated with it. A tag
is just a string of characters, and it may take any
form except that
of an integer. For example, ��x123�� is OK but
��123�� isn�t. The
same tag may be associated with many different items.
Furthermore, the site www.pythonware.com is a third-party
site not run by the Python developers. The official Python
documentation
(http://docs.python.org/lib/module-Tkinter.html and 'pydoc
Tkinter') doesn't explain the syntax of an item tag anywhere
that I could see)
I recommend closing this bug and notifying pythonware.com /
Fredrik Lundh about the problem via e-mail.
