Questions and Answers

What is the purpose of exception handling in object-oriented programming using Python?

To handle runtime errors and exceptions in a program, making it more robust and fault-tolerant.

What is the concept of inheritance in object-oriented programming?

A mechanism where a new class (subclass) inherits the attributes and methods of an existing class (superclass).

What is the observer pattern used for in design patterns?

To define a one-to-many dependency between objects, allowing them to react to changes in the state of another object.

Exception Handling (Python)

A programming technique to handle runtime errors (exceptions) gracefully in Python, preventing program crashes.

Inheritance (OOP)

A way to create new classes (subclasses) based on existing classes (superclasses), reusing their properties and methods.

Observer Pattern

A design pattern implementing a one-to-many dependency between objects so that when one object changes state, all its dependents are updated automatically.
