Sure enough it did. The question is - does importing into a function
ever make sense? It occurred to me that if you use from module

Can't be done. Locals of a function are all known at compile time.
That depends. 2.x issues a warning and disables optimization, so the
function's locals use a dict:
>>> from inspect import CO_OPTIMIZED
>>> def f(): from Tkinter import *
...
<stdin>:1: SyntaxWarning: import * only allowed at module level
>>> f.__code__.co_flags & CO_OPTIMIZED
0
I'm not saying this is a good idea. It isn't compatible with 3.x, you
lose the ability to create a closure (i.e. a nested function with free
variables), you lose the efficiency of the fast locals array, and
every call has to create and update a locals dict.
All good points. But Jim Mooney is running Python 3.3, as evidenced by
the location he gives for the interpreter.
