Enhancing Custom Exceptions in Python

Introduction:

In Python, exceptions play a crucial role in handling errors and exceptional situations that may occur during the execution of a program. While Python comes with a wide range of built-in exceptions designed to address common error scenarios, there are times when developers need to create custom exceptions to deal with unique or specific situations in their code.

Custom exceptions can not only improve the clarity of your code, but also make it easier for you and your team to debug and maintain the codebase. One way to enhance custom exceptions is by including additional information, such as the line number and method name where the error occurred. This can greatly aid in the process of identifying, locating, and fixing errors, particularly in larger projects or when working with multiple developers.

In this article, we will walk you through the process of creating a custom exception class that encapsulates the line number and method name in which the error took place. We will also demonstrate how to use this custom exception in a sample function, showing its benefits in error handling and debugging. By the end of this article, you will have a better understanding of how custom exceptions can be used effectively in your Python projects, and how they can be enriched with valuable diagnostic information.
