Exception Handling in Python: try & except, finally, and custom exceptions

Introduction:

Exception handling is a fundamental skill for every Python programmer. It allows programmers to handle errors and unexpected situations that can arise during program execution. In this article, we will dive into the world of possible errors in Python, exception handling, exploring the concepts of try and except, finallyand even creating custom exceptions. By the end of this guide, you'll be equipped with the knowledge to tackle errors effectively and build more robust and user-friendly applications.

Try and Except:

Python’s try and except statements provide a safety net for your code, allowing you to catch and handle exceptions that might occur during execution. This prevents your program from crashing and provides an opportunity to recover gracefully.

try:
    dividend = 10
    divisor = 0
    result = dividend / divisor
except ZeroDivisionError:
    print("Error: Division by zero is not allowed.")

In this example, a ZeroDivisionError is anticipated, and the except block captures it. This approach ensures that even though a zero division is attempted, the program continues to run, and a helpful error message…
