How can I create custom error pages in my Flask app?

You can create custom error pages in Flask by defining error handlers for specific HTTP status codes. For example, you can use the @app.errorhandler decorator.

Can you show me an example of how to implement a 404 error page?

Sure! You can add the following code to your Flask app:

@app.errorhandler(404)
def not_found(error):
    return render_template('404.html'), 404

Make sure you have a 404.html template in your templates folder.

What about customizing the 500 error page?

For a 500 error, you can do something similar:

@app.errorhandler(500)
def internal_error(error):
    return render_template('500.html'), 500

Again, ensure you have a 500.html template.

Can I use different templates for different error codes?

Yes, you can create different templates for each error code by defining separate error handlers for each status code you want to customize.
