c1 = child("P1", "P2", "C")
c1.show_parent1()
c1.show_parent2()

c1.child_name()

My output is

The name of parent1 is P2

How to override __init__ method in multiple inheritance?

I can easily override the __init__ method for single inheritance but was not able to do it for this.

    Rule number one of using `super`: it supports *cooperative* inheritance, which means *all* classes in the hierarchy need to use it correctly. That means `Parent1` and `Parent2` need to use it as well. `super` is misnamed; it does not always refer to a parent of the class you are writing, but rather the *next* class in the method resolution order of the object calling the method. – chepner Jan 14 '22 at 15:39
