Python for OOP - The A to Z OOP Python Programming Course - Naming Convention

This video tutorial covers naming conventions in Python, focusing on the distinction between public and private variables. It explains how naming conventions help developers understand code better, especially in large projects. The tutorial includes practical examples of implementing classes and methods, and introduces Dunder methods, which will be explored further in the next lecture.

What is the default visibility of variables in Python?

• Internal

• Public

• Protected

• Private

Why are naming conventions important in Python?

• They are required by the Python interpreter.

• They improve the performance of the code.

• They help developers understand the purpose of variables.

• They enforce strict access control.

How can you indicate a variable is intended to be private in Python?

• By using a double underscore prefix.

• By using a single underscore prefix.

• By using a 'private' keyword.

• By using a 'protected' keyword.

What is the purpose of the 'apply_discount' method in the example?

• To delete the phone object.

• To increase the price of the phone.

• To apply a discount to the phone's price.

• To change the phone's model.

What happens if you change the value of a variable marked as private by convention?

• The value can be changed as it is still public.

• The variable becomes protected.

• Python will throw an error.

• The program will crash.

What is a Dunder method in Python?

• A method with a single underscore prefix.

• A method that is public by default.

• A method with a double underscore prefix and suffix.

• A method that is private by default.

What is the significance of using naming conventions in a collaborative environment?

• They are mandatory for all Python projects.

• They help maintain code readability and consistency.

• They are used to encrypt the code.

• They increase the execution speed of the program.
