From 59d1d2b434e8cf79e8b1321f148254c68f56c1f7 Mon Sep 17 00:00:00 2001 From: Guido van Rossum Date: Fri, 20 Apr 2001 19:13:02 +0000 Subject: Iterators phase 1. This comprises: new slot tp_iter in type object, plus new flag Py_TPFLAGS_HAVE_ITER new C API PyObject_GetIter(), calls tp_iter new builtin iter(), with two forms: iter(obj), and iter(function, sentinel) new internal object types iterobject and calliterobject new exception StopIteration new opcodes for "for" loops, GET_ITER and FOR_ITER (also supported by dis.py) new magic number for .pyc files new special method for instances: __iter__() returns an iterator iteration over dictionaries: "for x in dict" iterates over the keys iteration over files: "for x in file" iterates over lines TODO: documentation test suite decide whether to use a different way to spell iter(function, sentinal) decide whether "for key in dict" is a good idea use iterators in map/filter/reduce, min/max, and elsewhere (in/not in?) speed tuning (make next() a slot tp_next???) --- Include/Python.h | 1 + 1 file changed, 1 insertion(+) (limited to 'Include/Python.h') diff --git a/Include/Python.h b/Include/Python.h index b771c8cf70..2393872004 100644 --- a/Include/Python.h +++ b/Include/Python.h @@ -82,6 +82,7 @@ #include "traceback.h" #include "sliceobject.h" #include "cellobject.h" +#include "iterobject.h" #include "codecs.h" #include "pyerrors.h" -- cgit v1.2.1
