Decorator question

[Steven W. Orr]

I just discovered decorators. Very cool. My question is that I can't 
figure out how to make a decorator not be restricted to a function so it 
would also work on a method.

Here's my code:

def g(expr):
     def rpt(func):
         def wrapper(t):
             for ii in range(expr):
                 print ii,
                 func(t)
             wrapper.__name__ = func.__name__
             wrapper.__dict__ = func.__dict__
             wrapper.__doc__ = func.__doc__
             return func
         return wrapper
     return rpt

@g(20)
def f(s):
     print 's="%s"'%s
f('Hello')

It works fine, but now I want to apply the same decorator to a class 
method.

class KK:
     # @g(20) This obviously doesn't work.
     def f(self, s):
         print 's= %s'%s

k = KK()
k.f('Hello')

Is there a trick I need?

TIA
