Handling Errors Gracefully in Python with try, except, and finally

Introduction

Road to become a Python Ninja — Handling Exceptions | by VJ | Medium

Error handling is a critical aspect of robust software development. Python provides a straightforward and flexible approach to handle errors using try, except, and finally blocks. This blog post will guide you through these constructs, helping you write more resilient code.

The try Block

The try block allows you to test a block of code for errors. If an error occurs, it is intercepted, and the flow of control is transferred to the corresponding except block.

Output:

Multiple except Blocks

You can handle different exceptions separately using multiple except blocks:

Output:

The finally Block

The finally block is optional and will always execute, regardless of whether an error occurred or not. It is commonly used for cleanup actions, such as closing files or releasing resources.

Output:

The else Block

An else block can be added after the except block(s). It runs if no exceptions are raised in the try block:

Output:

Raising Exceptions

You can raise exceptions manually using the raise keyword:
