Raymond Hettinger d449eab1e4 Fixed dotted name assertion. 2003-05-22 16:32:58 +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 341deb74e7 The previous made the stop argument optional.
It is better to be explicit and just allow stop to be None.

Raymond Hettinger 14ef54cd83 SF bug #730685: itertools.islice stop argument is not optional

Raymond Hettinger 1da1dbf458 Renamed PyObject_GenericGetIter to PyObject_SelfIter
to more accurately describe what the function does.

Suggested by Thomas Wouters.

Raymond Hettinger d1a283be26 Several of the tools can make direct calls the inner iterators. 2003-03-01 01:48:24 +00:00
Raymond Hettinger 61fe64d5de User requested changes to the itertools module.
Subsumed times() into repeat().
Added cycle() and chain().

Guido van Rossum d58f3fce3d Remove unused variable. 2003-02-09 17:19:18 +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 f0c00241ae * Eliminated tuple re-use in imap(). Doing it correctly made the code
too hard to read.
* Simplified previous changes to izip() to make it easier to read.

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()
