Tuple assignment and generators?

[Ant]

I don't think he was explicitly wanting to initialize things to zero,
but rather unpack an arbitrary sequence into a tuple (could perhaps be
the fibonnacci sequence for example).

How about:

>>> def zeros(count):
...     for i in range(count):
...         yield 0
...
>>> a,b,c = zeros(3)
>>> a
0
>>> b
0
>>> c
0
