Raymond Hettinger 354433a59d SF patch #872326: Generator expression implementation 
(Code contributed by Jiwon Seo.)

The documentation portion of the patch is being re-worked and will be
checked-in soon.  Likewise, PEP 289 will be updated to reflect Guido's
rationale for the design decisions on binding behavior (as described in
in his patch comments and in discussions on python-dev).

The test file, test_genexps.py, is written in doctest format and is
meant to exercise all aspects of the the patch.  Further additions are
welcome from everyone.  Please stress test this new feature as much as
possible before the alpha release.

Raymond Hettinger ade08ea8a8 Add news entries for the dictionary optimizations. 2004-03-18 09:48:12 +00:00
Raymond Hettinger b7d05db0be Optimize tuple_slice() and make further improvements to list_slice() 
and list.extend().  Factoring the inner loops to remove the constant
structure references and fixed offsets gives speedups ranging from
20% to 30%.

Raymond Hettinger dd80f76265 SF patch #910929: Optimize list comprehensions 
Add a new opcode, LIST_APPEND, and apply it to the code generation for
list comprehensions.  Reduces the per-loop overhead by about a third.
 2004-03-07 07:31:06 +00:00
Raymond Hettinger 31017aed36 SF #904720: dict.update should take a 2-tuple sequence like dict.__init_ 
(Championed by Bob Ippolito.)

The update() method for mappings now accepts all the same argument forms
as the dict() constructor.  This includes item lists and/or keyword
arguments.
 2004-03-04 08:25:44 +00:00
Raymond Hettinger 79b5cf1129 Mention the optimization of list.extend(). 2004-02-17 10:46:32 +00:00
Raymond Hettinger ab517d2eac Fine tune the speed/space trade-off for overallocating small lists. 
The Py2.3 approach overallocated small lists by up to 8 elements.
The last checkin would limited this to one but slowed down (by 20 to 30%)
the creation of small lists between 3 to 8 elements.

This tune-up balances the two, limiting overallocation to 3 elements
(significantly reducing space consumption from Py2.3) and running faster
than the previous checkin.

The first part of the growth pattern (0, 4, 8, 16) neatly meshes with
allocators that trigger data movement only when crossing a power of two
boundary.  Also, then even numbers mesh well with common data alignments.

Typo fixes; minor tweaks

Raymond Hettinger ed54d91ef5 Various fixups: 
* Add comment on the future of the sets module.
* Change a variable from "input" to "data" to avoid shadowing a builtin.
* Added possible applications for str.rsplit() and itertools.tee().
* Repaired the example for sorted().
* Cleaned-up the example for operator.itemgetter().

* highlight commonalities with SQL's groupby and Unix's uniq,
* demonstrate valid uses for the default identity function,
* add some excitement by suggesting the range of possibilities.
