Master Encapsulation in Python with Real-Life Examples | OOP Concepts Made Simple #interview #learn

🔒 Learn Python Encapsulation Made Simple!

In this step-by-step tutorial, we’ll uncover the power of Encapsulation in Python, one of the core principles of Object-Oriented Programming (OOP). Encapsulation ensures data security by hiding sensitive information inside objects and exposing only the essential details through public methods.

What You’ll Learn in This Video:
1️⃣ What is encapsulation, and why is it important in OOP?
2️⃣ How to use private attributes to hide data in Python classes.
3️⃣ Real-world example: Implementing encapsulation in a bank account system.
4️⃣ How to access private data securely using getter methods.
5️⃣ Why direct access to private attributes raises an error.

Code Example Walkthrough:
We’ll walk you through a bank account example that demonstrates:
✅ Creating private attributes (__balance).
✅ Protecting sensitive information.
✅ Using getter methods (get_balance()) to access private data safely.
✅ Adding methods to modify private data (deposit()).

Python Code Example:

class BankAccount:
def __init__(self, account_holder, balance):
self.__balance = balance # Private Attribute

def deposit(self, amount):
if amount GreaterThan 0:
self.__balance += amount

def get_balance(self):
return self.__balance

# Creating an account
account = BankAccount("John", 1000)

Why Learn Encapsulation?
Encapsulation allows developers to:

Protect sensitive data from accidental modification.
Maintain control over how data is accessed and modified.
Simplify debugging and troubleshooting by isolating internal object details.
