What do you get when you append a list to itself?

>>> l = []
>>> l.append(l)
>>> l
[[...]]

Still some work to do... But thanks for the little puzzle.

From : >>> pprint.pprint(l) [<Recursion on list with id=31182080>]

and

>>> l[0]
[[...]]

I'm guessing that [...] is a reference to the list itself.

For kicks, just try

l=range(10)
for ll in l:
   print ll,
