Re: [Python-Dev] enum discussion: can someone please summarize open issues?

2013年4月28日 12:58:19 -0700

Example enumeration:
class Seasons(Enum):
 SPRING = 1
 SUMMER = 2
 AUTUMN = 3
 WINTER = 4
 days_in_year = 365
 @property
 def avg_temp(self):
 return (75, 92, 66, 33)[int(self)+1] # enums are 1-based
Definite Issues:
 - should enum items be of the type of the Enum class? (i.e. type(SPRING) is 
Seasons)
 - should an enum item be selectable via __call__ instead of __getitem__ (i.e. 
Seasons(3) is AUTUMN)
 - should days_in_year be enumerated?
 - should avg_temp be enumerated?
 - for the above two, how should they be included/excluded?
