Python singleton again / how to use class attributes? -


i have singleton class in python java "static class attributes". read several posts existing on python singletons , can not find solution except using simple module singleton.

is there way extends code (pep318) use "static class attributes" can access functions?

def singleton(cls):     instances = {}     def getinstance():         if cls not in instances:             instances[cls] = cls()         return instances[cls]     return getinstance  @singleton class myclass:     ...

tbh, i've found singleton anti-pattern.

if want object ever have single instance, why bother instantiating anything? like...

class mycounter(object):     count = 0      @classmethod     def inc(cls, delta=1):         cls.count += delta  >>> mycounter.count 0 >>> mycounter.inc() >>> mycounter.count 1 >>> mycounter.inc(5) >>> mycounter.count 6
