Error Handling Fundamentals

Understanding error handling is crucial for building robust and reliable applications. In this guide, we will cover the basics of error handling in our system.

Common Errors

Here are some common errors you might encounter:

404 Not Found: This error occurs when the requested resource is not available on the server.
500 Internal Server Error: This error indicates that a technical problem prevented the server from fulfilling the request.
400 Bad Request: This error occurs when the request sent to the server is malformed or cannot be understood.

Handling Errors

To handle errors effectively, you should:

Log Errors: Always log errors for future reference and debugging purposes.
Respond Appropriately: Provide clear and informative error messages to the users.
Use Exception Handling: Implement exception handling to gracefully handle unexpected errors.

Example

Here's an example of how to handle a 404 error:

try:
    # Your code here
except FileNotFoundError:
    return "404 Not Found: The requested resource was not found."
