# Introduction Welcome to this unique programming challenge where you get to learn and apply error handling in Flask, a popular web framework in Python. Errors and exceptions are common when dealing with user input on the web. Handling these effectively allows you to ensure that your application continues to work correctly and efficiently even in the face of incorrect or unexpected user input. In this challenge, we are going to provide a basic Flask application where users can add, retrieve, and delete items. Your task will be to add error handling to this application to manage cases where the input from the user is incorrect or not as expected.
