How can I handle errors in Django and Flask applications?

In Django, you can use middleware to catch exceptions and return custom error pages. In Flask, you can use error handlers.

Can you give me an example of error handling in Flask?

Sure! You can define an error handler like this:

@app.errorhandler(404)
def not_found(error):
    return 'Page not found', 404

What about Django? How do I create a custom error page?

In Django, you can create a custom 404 page by defining a view and setting the handler404 in your urls.py file.

Are there best practices for error handling in these frameworks?

Yes, always log errors, provide user-friendly messages, and avoid exposing sensitive information in error responses.
