I just found out about that recently too.
help(iter) shows this:
Help on built-in function iter in module __builtin__:
iter(...)
iter(collection) -> iterator
iter(callable, sentinel) -> iterator
Get an iterator from an object. In the first form, the argument
must
supply its own iterator, or be a sequence.
In the second form, the callable is called until it returns the
sentinel.
