Python Abstraction

1. What is Abstraction?

Abstraction means hiding complex details and showing only what is needed.

In simple words:
👉 User sees what to do
👉 User does not see how it works
👉 It makes code simple and clean

2. Real-Life Example

Think about a TV remote 📺

• You press ON

• TV starts

• You don’t know how electricity works inside

Same idea in Python.

3. Why Do We Use Abstraction?

✔ Hides complex logic
✔ Makes code easy to use
✔ Improves security
✔ Helps teamwork

4. Abstraction in Python

Python supports abstraction using:

• Abstract classes

• Abstract methods

We use the abc module.

5. Simple Abstraction Example (Basic Idea)

Example

👉 User only calls start().

6. Abstract Class and Abstract Method

An abstract class cannot create objects.

Example

7. Child Class Implements Abstract Method

Example

8. Another Abstraction Example

Example

9. What Happens If Method is Not Implemented?

Example

❌ Error – abstract method missing.

10. Difference Between Abstraction and Encapsulation

11. Common Beginner Mistakes

❌ Creating Object of Abstract Class

❌ Error.

❌ Forgetting @abstractmethod

👉 No abstraction.

12. Simple Practice Examples

Example 1: Payment System

Example 2: Login System

Example 3: Notification

13. Summary (Python Abstraction)

✔ Abstraction hides complexity
✔ Uses abstract classes
✔ Abstract methods must be implemented
✔ Improves code clarity
✔ Important OOP concept
