py> class C(object):
...     a = 1
...     b = 2
...     def f(self):
...         pass
...     def g(self):
...         pass
...
py> import inspect
py> for attr, value in C.__dict__.iteritems():
...     if inspect.isroutine(value):
...         print attr, value
...
g <function g at 0x00C10B70>
f <function f at 0x011AC4B0>

or:

py> for attr, value in vars(C).iteritems():
...     if inspect.isroutine(value):
...         print attr, value
...
g <function g at 0x00C10B70>
f <function f at 0x011AC4B0>

or if you want to include special methods:

py> for attr in dir(C):
...     value = getattr(C, attr)
...     if inspect.isroutine(value):
...         print attr, value
...
__delattr__ <slot wrapper '__delattr__' of 'object' objects>
__getattribute__ <slot wrapper '__getattribute__' of 'object' objects>
__hash__ <slot wrapper '__hash__' of 'object' objects>
__init__ <slot wrapper '__init__' of 'object' objects>
__new__ <built-in method __new__ of type object at 0x1E1AE6E8>
__reduce__ <method '__reduce__' of 'object' objects>
__reduce_ex__ <method '__reduce_ex__' of 'object' objects>
__repr__ <slot wrapper '__repr__' of 'object' objects>
__setattr__ <slot wrapper '__setattr__' of 'object' objects>
__str__ <slot wrapper '__str__' of 'object' objects>
f <unbound method C.f>
g <unbound method C.g>

This is probably useful for introspection at the Python prompt, but if 
you're planning on doing this in your code somewhere, you might present 
the problem you're trying to solve to the list, because this is likely 
not the best way to approach it...
