[issue2502] Add enum() example for named tuples

2008-03-29 Thread Raymond Hettinger 

Raymond Hettinger [EMAIL PROTECTED] added the comment:

Thanks for asking. This should not go into the collections module.

The concept makes more sense in statically compiled languages.  In 
Python, we typically write something like RED, ORANGE, YELLOW = range
(3) at the module level.  That is faster and still allows prefixing 
using the module name (for example, re.MULTILINE).

[issue2502] Add enum() example for named tuples

2008-03-28 Thread Wummel 

Wummel [EMAIL PROTECTED] added the comment:

The motivation for this patch is that documenting a single function
adding enum-like capabilities would hopefully eliminate the numerous
enum recipies already out there, each handling things a little different.

[issue2502] Add enum() example for named tuples

2008-03-28 Thread Amaury Forgeot d'Arc 

Amaury Forgeot d'Arc [EMAIL PROTECTED] added the comment:

Raymond, is this kind of recipes worth adding to the 'collections' module?

Maybe with the following form:

def enum(*valuenames):
 return namedtuple('Enum', valuenames)(*range(len(valuenames)))
