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__.

Raymond Hettinger 2950bca89c Fix-up indentation of sample code blocks for namedtuple mthod definitions. 2009-01-14 01:39:51 +00:00
Raymond Hettinger 59894127e4 Minor doc tweaks. 2009-01-14 00:15:21 +00:00
Raymond Hettinger fbcf749479 Add table of idioms/patterns for using Counter objects. 
Improve the appearance and flow of the References section -- it used
to have a box around it that wasn't distinct from the preceding code
boxes and it had a weird bolding pattern and hanging indents that
made the section disproportionately large.

Raymond Hettinger 8278385a05 Minor documentation tweaks and simpler update() example. 2009-01-13 03:49:43 +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.
