Raymond Hettinger 1166872006 Small code simplification. Forgot that classmethods can be called from intances. 2008-01-06 09:02:24 +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.

Guido van Rossum 64c06e327d Backport of _abccoll.py by Benjamin Arangueren, issue 1383.

Raymond Hettinger 5681cbce81 Small improvement to the implementation of __replace__(). 2007-11-15 02:55:42 +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.

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.

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.
