Yeah, that code will almost certainly break in 2.2 when nested scopes
become mandatory.  It may have been intended, but assignment to a
local variable overshadowing a global is rarely the intended effect.

Anyways, if you want to get rid of those message now, without changing
the code use the  -W option to the interpreter.  Example :

$ python -W ignore Scope.py

(I created a file called Scope.py with that code in it)
