Python for OOP - The A to Z OOP Python Programming Course - Method Overriding and MRO

This video tutorial covers object-oriented programming methods, focusing on Method Resolution Order (MRO) and method overriding. It explains the concepts of classes, methods, and inheritance using a Phone class example. The tutorial demonstrates creating objects and using methods, and provides a detailed explanation of MRO in Python, showing how Python searches for methods in a class hierarchy. It also covers method overriding, illustrating how to add new functionality to existing methods.

What is the primary purpose of Method Resolution Order (MRO) in object-oriented programming?

• To determine the order of method execution in a single class

• To create new classes from existing ones

• To reduce the complexity of inheritance by defining the order of method lookup

• To override methods in a subclass

Which keyword is used to access attributes from a parent class in Python?

• super

• this

• base

• parent

In the context of MRO, what is the order in which Python searches for a method?

• In the order classes were defined

• In alphabetical order of class names

• From the bottommost class to the top

• From the topmost class to the bottom

How can you view the Method Resolution Order of a class in Python?

• By using the help function

• By using the print function

• By using the type function

• By using the dir function

What happens when a method is overridden in a subclass?

• The method in the parent class is deleted

• The method in the subclass is ignored

• The method in the subclass is executed instead of the parent class method

• Both methods are executed simultaneously

Why does Python prioritize methods in the order defined by MRO?

• To execute methods in the order they were defined

• To execute methods based on their length

• To execute methods in alphabetical order

• To ensure the most specific method is executed first

What additional information was added to the full name method in the Flagship class?

• RAM information

• Screen size

• Battery life

• Processor type
