As it has been said before, using self.methodX() seems to be solving your problem. Check this:
class A(object):
def methodX(self):
print "A.methodX"
def methodY(self):
print "A.methodY"
self.methodX()
class B(A):
def methodZ(self):
print "B.methodZ"
self.methodY()
b = B()
b.methodZ()
Generates this output:
$ python test.py
B.methodZ
A.methodY
A.methodX
$
Which I think it's what you were looking for...
