Jeremy Hylton	fbbe34789e	Add a useful docstring to enumerate.	2003-04-21 20:26:25 +00:00
Raymond Hettinger	1da1dbf458	Renamed PyObject_GenericGetIter to PyObject_SelfIter ... to more accurately describe what the function does. Suggested by Thomas Wouters.	2003-03-17 19:46:11 +00:00
Raymond Hettinger	0153826964	Created PyObject_GenericGetIter(). ... Factors out the common case of returning self.	2003-03-17 08:24:35 +00:00
Guido van Rossum	ca5ed5b875	Remove the next() method -- one is supplied automatically by ... PyType_Ready() because the tp_iternext slot is set (fortunately, because using the tp_iternext implementation for the the next() implementation is buggy). Also changed the allocation order in enum_next() so that the underlying iterator is only moved ahead when we have successfully allocated the result tuple and index.	2002-07-16 21:02:42 +00:00
Martin v. Löwis	14f8b4cfcb	Patch #568124: Add doc string macros.	2002-06-13 20:33:02 +00:00
Guido van Rossum	7dab2426ca	- New builtin function enumerate(x), from PEP 279. Example: ... enumerate("abc") is an iterator returning (0,"a"), (1,"b"), (2,"c"). The argument can be an arbitrary iterable object.	2002-04-26 19:40:56 +00:00
