Using property() on classmethods

Question

I have a class with two class methods (using the classmethod() function) for getting and setting what is essentially a static variable. I tried to use the property() functi

Answer 1

Give this a try, it gets the job done without having to change/add a lot of existing code.

>>> class foo(object):
...     _var = 5
...     def getvar(cls):
...         return cls._var
...     getvar = classmethod(getvar)
...     def setvar(cls, value):
...         cls._var = value
...     setvar = classmethod(setvar)
...     var = property(lambda self: self.getvar(), lambda self, val: self.setvar(val))
...
>>> f = foo()
>>> f.var
5
>>> f.var = 3
>>> f.var
3

The property function needs two callable arguments. give them lambda wrappers (which it passes the instance as its first argument) and all is well.
