Raymond Hettinger dbe3d280e7 Adopt Christian Stork's suggested argument order for the logic quantifiers.
Adopt Jeremy Fincher's suggested function name, "any", instead of "some".

Raymond Hettinger 42a61ed277 Simplify doctest of tee(). 2003-09-13 01:01:34 +00:00
Raymond Hettinger a098b33c93 Add an example to address a common question of how to split iterators. 2003-09-08 23:58:40 +00:00
Raymond Hettinger a56f6b6600 SF bug #793826: using itertools.izip to mutate tuples
Avoid Armin Rigo's dastardly exercise in re-entrancy.
2003-08-29 23:09:58 +00:00
Raymond Hettinger b5a420883c Modified itertools.izip() to match the behavior of __builtin__.zip()
which can now take zero arguments.

Raymond Hettinger 77fe69bd08 Re-sync doc tests with the doc updates. 2003-08-08 04:33:19 +00:00
Raymond Hettinger 0242070d04 More tests
* Test with infinite inputs (using take() on the output)
* Test whether GC can find and eliminate cycles.
2003-06-29 20:36:23 +00:00
Raymond Hettinger 3567a876c7 Add take() to examples. Tighten the islice() example 2003-06-28 05:44:36 +00:00
Raymond Hettinger befa37dd05 Minor updates:
* Updated comment on design of imap()
* Added untraversed object in izip() structure
* Replaced the pairwise() example with a more general window() example

Raymond Hettinger f0fa1c03a0 Test ability to handle various type of iterators. 2003-05-29 07:18:57 +00:00
Raymond Hettinger 929f06c570 Minor cleanups. 2003-05-16 23:16:36 +00:00
Raymond Hettinger 7c2bb5bc57 * Added a substantial number of edge case and argument tests for
the itertoolsmodule.
* Taught itertools.repeat(obj, n) to treat negative repeat counts as
  zero.  This behavior matches that for sequences and prevents
  infinite loops.

Raymond Hettinger 8fd3f871f3 Add StopIteration tests.
Simplify test_main().
2003-05-02 22:38:07 +00:00
Raymond Hettinger 341deb74e7 The previous made the stop argument optional.
It is better to be explicit and just allow stop to be None.
2003-05-02 19:44:20 +00:00
Raymond Hettinger 14ef54cd83 SF bug #730685: itertools.islice stop argument is not optional
* itertools.islice() stop argument did not perform as documented.
* beefed-up test suite
2003-05-02 19:04:37 +00:00
Walter Dörwald 21d3a32b99 Combine the functionality of test_support.run_unittest()
and test_support.run_classtests() into run_unittest()
and use it wherever possible.

Also don't use "from test.test_support import ...", but
"from test import test_support" in a few spots.

From SF patch #662807.
2003-05-01 17:45:56 +00:00
Raymond Hettinger 61fe64d5de User requested changes to the itertools module.
Subsumed times() into repeat().
Added cycle() and chain().
2003-02-23 04:40:07 +00:00
Raymond Hettinger 60eca9331a C Code:
* Removed the ifilter flag wart by splitting it into two simpler functions.
* Fixed comment tabbing in C code.
* Factored module start-up code into a loop.

Documentation:
* Re-wrote introduction.
* Addede examples for quantifiers.
* Simplified python equivalent for islice().
* Documented split of ifilter().

Sets.py:
* Replace old ifilter() usage with new.

Raymond Hettinger 2012f174ea SF bug #681003: itertools issues
* Fixed typo in exception message for times()
* Filled in missing times_traverse()
* Document reasons that imap() did not adopt a None fill-in feature
* Document that count(sys.maxint) will wrap-around on overflow
* Add overflow test to islice()
* Check that starmap()'s argument returns a tuple
* Verify that imap()'s tuple re-use is safe
* Make a similar tuple re-use (with safety check) for izip()
