calling child class method from parent class file in python

Question

parent.py:

class A(object):
    def methodA(self):
        print(\"in methodA\")

child.py:

from paren         


        

Answer 1

You could use the function anywhere so long as it was attached to an object, which it appears to be from your sample. If you have a B object, then you can use its methodb() function from absolutely anywhere.

parent.py:

class A(object):
    def methoda(self):
        print("in methoda")

def aFoo(obj):
  obj.methodb()

child.py

from parent import A
class B(A):
    def methodb(self):
        print("am in methodb")

You can see how this works after you import:

>>> from parent import aFoo
>>> from child import B
>>> obj = B()
>>> aFoo(obj)
am in methodb

Granted, you will not be able to create a new B object from inside parent.py, but you will still be able to use its methods if it's passed in to a function in parent.py somehow.
