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__.

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.

Improve namedtuple's _cast() method with a docstring, new name, and error-checking.
2008-01-05 01:35:43 +00:00
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.

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.

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.

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.
