This document explores debugging Python programs using try-except blocks to handle runtime errors gracefully. Topics include catching specific exceptions, creating custom exceptions, using finally clauses, accessing exception details, and best practices for proper exception handling without swallowing errors.

Introduction

Try-except (often called “try-catch” in other languages) is a common programming paradigm for handling runtime errors or exceptions gracefully without crashing programs. This mechanism allows developers to anticipate potential errors and respond appropriately, whether by logging the error, informing users, or attempting recovery actions.

This document covers HTTP status codes, error handling in Flask, and best practices for returning error responses from API endpoints. It explains status code categories, custom error responses, and application-level error handlers for robust API design.

Understanding HTTP Status Codes

Every HTTP response includes a three-digit status code that indicates the result of the request. Status codes are grouped into categories:

Code Range	Category	Description
100–199	Informational	Request received, continuing process
200–299	Success	Request received and processed successfully
300–399	Redirection	Further action needed to complete request
400–499	Client Error	Error in the request from the client
500–599	Server Error	Error on the server side

Common codes include:
