Python methods and C++ static methods

[Yann Cointepas]

Can Python unbound methods easily be used like C++ static methods ?

The problem is that unbound methods must be called with instance as first 
argument. Therefore the following code fails.

>>> class C:
...   def static_method( i ):
...     return 2 * i
...
>>> x = C.static_method( 3 )
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: unbound method static_method() must be called with instance as 
first argument

I would like to keep 'static_method' in 'C' attributes but I think that it 
is not possible. Am I wrong ? If I am not, I plan to use the following code:

class C:
  class foo:
    def static_method( self, i ):
       return 2 * i
  static = foo()

x = C.static.static_method( 3 )

Is there a better solution ?

Thanks for any help.
