Line profiling class instantiation in python

I have some existing code that I'm trying to profile. I can successfully line profile class methods by adding a @profile decorator, and using kernprof.

Is there a general way to profile class instantiation? I have a few classes that have a quite complex inheritance structure. When I try to profile their init functions I get something like this:

Line #      Hits         Time  Per Hit   % Time  Line Contents
==============================================================
   179                                               def __init__(self, data):
   180         1    8910739.0 8910739.0    100.0          super().__init__(data)
   181         1         10.0     10.0      0.0          self.mortgage_rate = 5.2  # rate in percentage

Which is a bit useless, because I don't know what actual parent init function (this class has 2 parents, each of which have one or more parents) is being called.

Is there way way to do this better? For example, is there a way to automatically dive into each line, and profile the lines that get called by it (with limited depth?)
