Comparison and inheritance

What happens when an object is compared to an object of a child class? Consider the following two classes:

class Parent:
    def __eq__(self, other):
        print("Parent's __eq__() called")
        return True

class Child(Parent):
    def __eq__(self, other):
        print("Child's __eq__() called")
        return True

The Child class inherits from the Parent class, and both implement the __eq__() method that includes a diagnostic printout.
