Hacky, but maybe this will work:
import sys
import inspect
def mytrace(frame, event, arg):
if event == 'call':
func_name = frame.f_code.co_name
klassOb = frame.f_locals['self'].__class__
for klass in inspect.getmro(klassOb):
cf = klass.__dict__.get(func_name)
if hasattr(cf, "func_code") and cf.func_code == frame.f_code:
print klass.__name__
class A(object):
def __init__(self):
pass
class B(A):
def __init__(self):
A.__init__(self)
sys.settrace(mytrace)
B()
