Questions and Answers

What is the primary purpose of abstraction in Object-Oriented Programming (OOP)?

To inherit features from another class.

To define multiple forms of a method.

To increase the visibility of internal details of a class.

To hide implementation details and show only essential features. (correct)

Which statement accurately describes the difference between an abstract class and an interface in OOP?

Study Notes

Abstraction in OOP

Abstraction in object-oriented programming (OOP) focuses on hiding complex implementation details and showcasing only essential features.
This simplifies interaction with the class and its methods.

Abstract Class vs. Interface

Abstract classes can have both implemented and unimplemented methods.
Interfaces can't have implemented methods.
Interfaces can be instantiated, but abstract classes cannot.

Python Data Types

Tuples can store elements of different data types.
Sets are used for unique, unordered items.
The correct way to add an item to a Python list is list.append(item).

Python Dictionaries

Dictionary keys can hold duplicate values.
Dictionary values can have duplicates.

Python Functions

Functions can have multiple return statements.
Functions can have default arguments.

Python Variable Naming

Avoid naming variables after built-in types (e.g., str) to prevent shadowing errors.

Error Handling

ZeroDivisionError occurs when dividing by zero during a program execution.

Object-Oriented Programming Principles

Encapsulation, Inheritance, and Polymorphism.
