Checking length of each argument - seems like I'm fighting Python

Disclaimer: I am new to python, so this may be a bad solution.

import types
def __init__(self,x,y,z):
    isOK = False
    if ( (type(x) == types.IntType) and (type(y) == types.IntType) and (type(z) == types.IntType) ):
	isOK = True
    if ( (type(x) == types.ListType) and (type(x) == types.ListType) and (type(x) == types.ListType) ):
    	if ( (len(x) == len(y)) and (len(x) == len(z)) ):
	    isOK = True

HTH,
