How we can extend multiple Python classes in inheritance?
As per Python documentation ‘super’ can help in extending multiple python classes in inheritance. It returns a proxy object that delegates method calls to a parent or sibling class of type. This is useful for accessing inherited methods that have been overridden in a class. The search order is same as that used by getattr() except that the type itself is skipped.
In other words, a call to super returns a fake object which delegates attribute lookups to classes above you in the inheritance chain. Points to note:
This does not work with old-style classes.You need to pass your own class and instance to super in Python 2.x. This requirement was waived in 3.x.
This will handle all multiple inheritance correctly. A method resolution order is generated and the lookups go through parent classes in this order.
