How to search for a function/class within a module?

I want to know if a function/class exists somewhere in a module. I do know how to generate a list of all the classes/functions that are at the upper level/hierarchy of the module using dir() For example, let's say I want to know if function now() exists inside the datetime module: 

import datetime
dir(datetime)

But this does not list the function now() because now() is contained in a deeper level (in datetime.datetime to be exact). How do I check if now() exists or not? Or maybe there is a way to list everything from all the levels?

This piece of code lists the contents of modules recursively. Note however it will fail if two submodules/objects/... share the same name

import time
import datetime

pool=[] # to avoid loops 

def recdir(d,n=''):
    children_all=dir(d)
    children=[c for c in children_all if c[0]!='_' and not c in pool]
    for child in children:
        pool.append(child)
        full_name=n+"."+child
        print "Found: ","'"+full_name+"' type=",eval("type("+full_name+")")
        string="recdir(d."+child+",'"+full_name+"')"
        print "Evaluating :",string
        time.sleep(0.2)
        eval(string)

recdir(datetime,'datetime')
