How to Inherit multiple classes in python dynamically [duplicate]

Can any one help me to inherit multiple classes in python.

Let say I have three classes in three different modules.

a.py :

class A():
   def __init__(self):
      pass

   def fruit(self):
     print "Apple is a fruit"

b.py :

class B():
    def __init__(self):
       pass

    def vegetable(self):
       print "Potato is a vegetable"

c.py :

class C():
  def __init__(self):
      pass

  def vehicle(self):
     print "Car is a vehicle"

I just want to configure all these class names in a file like , a.A , b.B and c.C. then read the configuration file and load the configured modules and inherit those modules( Multiple Inheritance ).

utility.py

Read configuration and get the modules.

class Utility(INHERIT_CONFIGURED_MODULES):
    def __init__(self):
       pass

obj = Utility()
obj.fruit()
obj.vegetable()
obj.vehicle()

Now ,If I create one more module and configure that in my configuration file,then I should access its methods using the objected created for Utility class.

Hope its clear.Please guide me to achieve this.
