Here is one way to do it...

def somefunc():
	print "I am a happy function"

class Foo:
	def __init__(self):
		self.f = somefunc
		
>>> foo = Foo()
>>> foo.f
<function somefunc at 00A53C0C>
>>> foo.f()
I am a happy function

This may not be exactly what you want though, because it binds f to the 
instance, rather than the class.

Here's another way, but it's kinda clumsy:

class Bar:
	funcs = [somefunc]
	
>>> bar = Bar()
>>> bar.funcs[0]
<function somefunc at 00A53C0C>
>>> bar.funcs[0]()
I am a happy function
