How can I implement custom error messages in Flask?

You can create custom error messages in Flask by using the @app.errorhandler decorator. This allows you to define how your application responds to specific HTTP errors.

Can you show me an example of how to do that?

Sure! Here's a simple example:

from flask import Flask, jsonify

app = Flask(__name__)

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

if __name__ == '__main__':
    app.run()

What about handling multiple error types?

You can handle multiple error types by adding more @app.errorhandler decorators for each error code. For example:

@app.errorhandler(500)
def internal_error(error):
    return jsonify({'error': 'Internal server error!'}), 500
