How can I format error responses in Flask?

In Flask, you can format error responses by creating custom error handlers. You can use the @app.errorhandler decorator.

Can you show me an example of a custom error handler?

Sure! Here's a simple example:

@app.errorhandler(404)
def not_found(error):
    return jsonify({'error': 'Not found'}), 404

What if I want to include more details in the error response?

You can include additional details by modifying the JSON response. For example:

@app.errorhandler(404)
def not_found(error):
    return jsonify({'error': 'Not found', 'message': 'The resource you requested does not exist.'}), 404

Is it possible to handle multiple error codes in one function?

Yes, you can handle multiple error codes by specifying them in a tuple:

@app.errorhandler((404, 500))
def handle_error(error):
    return jsonify({'error': str(error)}), error.code
