Object Orientation in Python

Full Answer Section

       

• Example: Python is a popular object-oriented language. In Python, you can define a class called Dog with attributes like name and age, and methods like bark(). You can then create multiple Dog objects, each with its own unique name and age, from this single class definition.

Exception Handling in Python

  In Python, an exception handling block is a construct used to handle runtime errors, or exceptions, that can occur during the execution of a program. Instead of crashing the program, the exception handling block allows the programmer to "catch" the error and execute a specific set of code to handle it gracefully. The main components of an exception handling block are try, except, else, and finally.  

Usage of Exception Handling

  This is crucial for writing robust and reliable code. It allows a program to continue running even if an unexpected error occurs. For instance, if a user tries to divide a number by zero or opens a file that doesn't exist, the program won't terminate abruptly.

Sample Answer

       

Object-Oriented Programming (OOP)

  An object-oriented language is a programming language that uses the concept of "objects" to design applications and computer programs. An object can contain both data (fields, attributes) and code (procedures, methods) that act on that data. The main goal of OOP is to increase the flexibility and maintainability of programs by modeling real-world entities.  

Usage of OOP

  OOP is used in a wide variety of applications, from developing large-scale enterprise systems to video games and mobile apps. It promotes the principles of encapsulation, inheritance, and polymorphism, which are key to creating reusable, modular, and organized code. For example, a developer can create a generic "Vehicle" object and then create more specific objects like "Car" and "Motorcycle" that inherit the properties and methods of the "Vehicle" object. This reduces code redundancy and makes the codebase easier to manage.
