I will clarify by starting over with current definitions.
Ob is an iterator iff next(ob) either returns an object or raises
StopIteration and continues to raise StopIteration on subsequent calls.
Ob is an iterable iff iter(ob) raturns an iterator.

Hi,
I'm trying to create a new class of list that has periodic boundary
conditions.
Here's what I have so far:
class wrappedList(list):
def __getitem__(self, p):
return list.__getitem__(self, p%len(self))
def __setitem__(self, p, v):
3-A,3-A2,7-A4...
and the two 78s would pair with a G and with a G2 (78-G, 78-G2)
beyond that I'm a bit lost.

The correct answer supposed to be A and A2...
if I were asked for pressures 56 and 78 the correct answer supossed to
be valves G and G2...
Valves = ['A','A&

d['a'] is ok, and a new set object is insert to d, but d.get('b') won't.
It's a bug, or just a feature?
Feature.

Or just use print.
>>> print 4.0/5.0
0.8
Since interactive prompt is usually used by programmers who are
inspecting values it makes a little more sense to

Thanks. Yes i tried something like this, but I think I overwrite `c`
when i wrote it, as in:
if len(c) > 0:
c = fin_node(c, name)
if c is not None:
return c
FYI, doing that won't actually matter in this case; 'c' will still be
bound to the n
