Help on class enumerate in module __builtin__:
class enumerate(object)
| enumerate(iterable) -> iterator for index, value of iterable
|
| Return an enumerate object. iterable must be an other object that supports
| iteration. The enumerate object yields pairs containing a count (from
| zero) and a value yielded by the iterable argument. enumerate is useful
| for obtaining an indexed list: (0, seq[0]), (1, seq[1]), (2, seq[2]), ...
|
| Methods defined here:
|
| __getattribute__(...)
| x.__getattribute__('name') <==> x.name
|
| __iter__(...)
| x.__iter__() <==> iter(x)
|
| next(...)
| x.next() -> the next value, or raise StopIteration
|
