Practical Python: Learn Python Basics Step by Step- Python 3 - Add Class Methods

The video tutorial explains how to implement methods in a class, focusing on the use of the 'self' parameter to access and modify class attributes. It covers creating a 'sayHi' method, initializing hardware, and printing information using class methods. The tutorial emphasizes the importance of linking methods to specific objects and classes, demonstrating how to call methods within a class and use attributes effectively.

What is the primary purpose of the 'self' parameter in class methods?

• To define a global variable

• To refer to the class itself

• To create a new class

• To access the current instance of the class

How is a method different from a regular function in Python?

• A method is not linked to any class

• A method is specifically associated with a class and its objects

• A method cannot take any parameters

• A method is always a global function

In the 'say Hi' method, what does 'self.name' represent?

• A method of the class

• An attribute of the class instance

• A global function

• A local variable

What is the purpose of calling 'self.say_hi()' within another method?

• To delete an attribute

• To call a global function

• To execute the 'say Hi' method of the class

• To create a new method

Why might you cast 'self.version_number' to a string in the 'print info' method?

• To ensure it is always treated as a string

• To convert it into a float

• To make it a global variable

• To delete the attribute
