How can I handle exceptions in Flask?

In Flask, you can handle exceptions using the @app.errorhandler decorator. This allows you to define custom error handling for specific HTTP error codes.

Can you show me an example of using @app.errorhandler?

Sure! Here's a simple example:

from flask import Flask, jsonify

app = Flask(__name__)

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

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

What about handling unexpected errors?

For unexpected errors, you can use a general error handler:

@app.errorhandler(Exception)
def handle_exception(e):
    return jsonify({'error': str(e)}), 500

How do I log these exceptions?

You can use Python's built-in logging module to log exceptions. Just configure the logger in your Flask app and log the errors in your error handlers.
