Python - Object-Oriented Programming - Different Methods Inside the Class

The video tutorial explains the three types of methods in Python classes: instance methods, class methods, and static methods. Instance methods can modify both object and class attributes, making them the most powerful. Class methods can only modify class attributes and are less powerful. Static methods, which do not modify object or class attributes, are the least powerful and serve as auxiliary tools. The tutorial provides examples and demonstrates how to use each method type effectively.

What are the three types of methods that can be defined in a Python class?

• Synchronous, Asynchronous, and Hybrid methods

• Local, Global, and Nonlocal methods

• Public, Private, and Protected methods

• Instance, Class, and Static methods

Which method type in Python classes can modify both object and class states?

• Static methods

• Global methods

• Instance methods

• Class methods

What is the first parameter typically used in instance methods?

• cls

• self

• obj

• this

How do class methods differ from instance methods in terms of parameters?

• Class methods use 'self' as the first parameter

• Class methods do not take any parameters

• Class methods use 'cls' instead of 'self'

• Class methods use 'this' as the first parameter

What is the purpose of the classmethod decorator in Python?

• To define a method that is only accessible within the class

• To define a method that does not take any parameters

• To define a method that can modify class attributes

• To define a method that can modify object state

Which method type is considered the least powerful in terms of modifying states?

• Class methods

• Instance methods

• Global methods

• Static methods

What is a key characteristic of static methods in Python classes?

• They do not take 'self' or 'cls' as parameters

• They can modify both object and class states

• They require an instance to be called

• They are always private to the class

How can static methods be accessed in Python?

• Only through global functions

• Only through class instances

• Only through the class itself

• Through both class instances and the class itself

Why might you choose to use a static method over an instance method?

• To provide utility functions that do not depend on object or class state

• To modify class attributes

• To ensure the method is private

• To modify object state

What is the main advantage of using the appropriate method type in Python classes?

• It reduces the number of lines of code

• It ensures the code is easier to understand and maintain

• It makes the code run faster

• It allows for more complex logic
