In this tutorial we will explore how to handle errors that may occur when making web requests in a Python application deployed on Google App Engine GAE. Web requests can fail for various reasons such as network issues server problems or invalid URLs. Handling these errors gracefully is crucial to ensure a robust and reliable application. Well use the requests library for making web requests and demonstrate how to handle common types of errors. To follow along make sure you have a Python environment set up with the requests library installed and have a basic understanding of Google App Engine. Python 3.x installed on your local machine. Install the requests library: A Google App Engine project. If you dont have one you can create one on the Google Cloud Console. First lets import the necessary modules for our Python application: Connection errors can occur when the target server is not reachable or there is a network problem. You can catch these errors using the requests.exceptions.RequestException class. In this example we attempt to make a GET request to and catch any exceptions that might occur. The raise_for_status method ensures that an HTTP error response e.g. 404 500 is treated as an error. You can handle HTTP errors more specifically by checking the HTTP status code. For example you may want to respond differently to a 404 Not Found error than a 500 Internal Server Error. This code will catch any HTTP error such as a 404 or 500 error. You can define custom error handling logic,
