How can I create custom error pages in Django and Flask?

In Django, you can create custom error pages by defining templates for specific HTTP error codes like 404 or 500. In Flask, you can use the @app.errorhandler decorator to handle errors and render custom templates.

Can you show me an example for Django?

Sure! First, create a template named 404.html in your templates directory. Then, in your urls.py, add a handler for 404 errors like this: handler404 = 'myapp.views.custom_404_view'.

What about Flask? How do I set that up?

In Flask, you can define a custom error handler like this: @app.errorhandler(404) and then create a function that returns your custom template for the 404 error.

Are there any best practices for designing these error pages?

Yes! Make sure your error pages are user-friendly, provide helpful information, and include links back to the homepage or other relevant pages.
