On the contrary. Functions and methods are first class types, so you
can move them around, store them, and call them as much as you like:
>>> def f(x):
... print x
...
>>> f
<function f at 0x81950bc>
>>> g = f
>>> g
<function f at 0x81950bc>
>>> f(1)
1
>>> g(1)
1
It even has both bound and unbound methods, something which, for
instance, C++ does not have:
>>> class C:
... def m(self, x):
... print x
...
>>> c = C()
>>> unbound = C.m
>>> unbound(c, 1) # must call with `self' argument explicitly
1
>>> bound = c.m
>>> bound(1) # `self' argument implied, not needed
