PYTHON Study Guide - Final Guide: Functional Programming, Business Class, Loose Coupling
#48 Python Tutorial for Beginners | Object Oriented
Programming | Introduction
Section Overview: In this section, the speaker introduces the series on
Python and discusses the language fundamentals of Python, including
variables, functions, and modules. The speaker then moves towards
discussing object-oriented programming (OOP) as a concept that is
important in the industry.
## Language Fundamentals of Python
- Variables are introduced as a fundamental concept in Python.
- Functions are discussed as a way to break down projects into smaller parts.
- Modules are introduced as a way to work with different files.
## Object-Oriented Programming (OOP)
- OOP is introduced as an important concept in the industry.
- Functional programming is defined as implementing tasks using functions
without manipulating data.
- Procedures and functions are discussed as concepts that have already
been covered.
- The importance of thinking about everything in terms of objects when
working on big software or enterprise projects is emphasized.
- Everything in the real world can be thought of as an object with attributes
(data/properties) and behavior (actions).
- Attributes are further defined as data or properties such as height, age,
name, etc.
-Behavior is defined by actions such as talking, walking, dancing etc.
- Objects will have something that stores data which we normally use
variables for.
- Methods are introduced as functions in object-oriented programming.

Introduction to Encapsulation and Abstraction
Section Overview: In this section, the speaker introduces the concepts of
encapsulation, abstraction, and polymorphism in object-oriented
programming.
## Importance of Objects and Classes
- Objects and classes are important concepts in object-oriented
programming.
- Objects are real-world entities that can be manufactured in large
quantities.
- Classes are designs or blueprints for creating objects.
## Designing Classes
- The design of an object is created in a class.
- A class is a blueprint or design for creating multiple instances of an object.
## Key Takeaways
- Encapsulation, abstraction, and polymorphism are important concepts in
object-oriented programming.
- Objects are real-world entities that can be manufactured in large
quantities.
- Classes provide the design or blueprint for creating objects.
