Benjamin Peterson 5c8da86f3a convert usage of fail* to assert* 2009-06-30 22:57:08 +00:00
Alexandre Vassalotti cb73bdac95 Revert r73401 per Raymond Hettinger's request. 
The rational is the change might cause imcompatiblity problems with
PyYAML. In addition, Raymond wants to kept the different versions of
collections synchronized across Python versions.

Raymond Hettinger bad1eb2ff3 Build-outs for Counter() class: 
* Constructor and update() support keyword args (like their dict counterparts).
* The 'del' statement no longer raises KeyError for missing values.
* Add multiset operations:  __add__, __sub__, __and__, __or__.
 2009-01-20 01:19:26 +00:00
Raymond Hettinger afd112baef Add tests for __init__() and update() with no args. 2009-01-14 01:15:06 +00:00
Raymond Hettinger aaa6e630f8 Simplify Counter() API. Replace items keyword argument 
with a mapping.  Makes Counter() idempotent, makes update()
API the same as Counter.__init__(), makes a more readable
repr, makes the API more dict-like, and allows Steven
Bethard's update() example to work.

Nick Coghlan 48361f5cbf Issue 2235: Py3k warnings are now emitted for classes that will no longer inherit a__hash__ implementation from a parent class in Python 3.x. The standard library and test suite have been updated to not emit these warnings. 2008-08-11 15:45:58 +00:00

Georg Brandl 0bb0299ad8 Take namedtuple item names only from ascii_letters (this blew up on OSX), 
and make sure there are no duplicate names.

Amaury Forgeot d'Arc cb0f2ad0c2 A DocTestSuite cannot run multiple times: it clears its globals dictionary after the first run. 
Rebuild the DocTestSuite on each iteration.
 2008-04-02 00:55:04 +00:00
Raymond Hettinger d1ef85420f Run doctests on the collections module 2008-01-11 00:23:13 +00:00
Raymond Hettinger 1b50fd7cb3 Add error-checking to namedtuple's _replace() method. 2008-01-05 02:17:24 +00:00
Raymond Hettinger 02740f73ff Improve namedtuple's _cast() method with a docstring, new name, and error-checking. 2008-01-05 01:35:43 +00:00
Raymond Hettinger e0734e7dc0 Minor fix-ups to named tuples: 
* Make the _replace() method respect subclassing.

* Using property() to make _fields read-only wasn't a good idea.
  It caused len(Point._fields) to fail.

* Add note to _cast() about length checking and alternative with the star-operator.

 2007-11-22 00:55:51 +00:00
Raymond Hettinger eeeb9c4445 Accept Issac Morland's suggestion for __replace__ to allow multiple replacements 
(suprisingly, this simplifies the signature, improves clarity, and is comparably fast).
Update the docs to reflect a previous change to the function name.
Add an example to the docs showing how to override the default __repr__ method.
 2007-11-15 02:44:53 +00:00

Raymond Hettinger a48a29947a Eliminate camelcase function name 2007-10-08 21:26:58 +00:00
Raymond Hettinger 2115bbc4da Add comments to NamedTuple code. 
Let the field spec be either a string or a non-string sequence (suggested by Martin Blais with use cases).
Improve the error message in the case of a SyntaxError (caused by a duplicate field name).
 2007-10-08 09:14:28 +00:00
Raymond Hettinger a7fc4b13e0 Add __asdict__() to NamedTuple and refine the docs. 
Add maxlen support to deque() and fixup docs.
Partially fix __reduce__().  The None as a third arg was no longer supported.
Still needs work on __reduce__() to handle recursive inputs.
 2007-10-05 02:47:07 +00:00
Raymond Hettinger 2b03d45bb9 Handle corner cased on 0-tuples and 1-tuples. Add verbose option so people can see how it works. 2007-09-18 03:33:19 +00:00
Raymond Hettinger d36a60e1e3 Sync-up named tuples with the latest version of the ASPN recipe. 
Allows optional commas in the field-name spec (help when named tuples are used in conjuction with sql queries).
Adds the __fields__ attribute for introspection and to support conversion to dictionary form.
Adds a  __replace__() method similar to str.replace() but using a named field as a target.
Clean-up spelling and presentation in doc-strings.
 2007-09-17 00:55:00 +00:00
