Q2. Oops concepts in python
Ans. 
Oops concepts in Python include inheritance, encapsulation, polymorphism, and abstraction.
• Inheritance allows a class to inherit attributes and methods from another class.

• Encapsulation restricts access to certain components within a class.

• Polymorphism allows objects to be treated as instances of their parent class.

• Abstraction hides complex implementation details and only shows the necessary features.

Q2. What is Encapsulation
Ans. 
Encapsulation is the process of hiding internal details and providing a public interface for accessing and manipulating data.
• Encapsulation bundles data and methods together into a single unit.

• It helps in achieving data abstraction and data hiding.

• By encapsulating data, we can control access to it and prevent unauthorized modifications.

• Encapsulation promotes code reusability and maintainability.

• Example: A class in objec...read more

• Polymorphism is a fundamental concept in object-oriented programming.

• It enables code reusability and flexibility.

• Polymorphism can be achieved through method overriding and method overloading.

• Example: A parent class Animal can have multiple child classes like Dog, Cat, and Bird. They can ...read more
