Certainly! To edit the error page in Flask, you can use error handlers. Here are the steps:

1. Create a Flask app: ```python from flask import Flask, render_template

app = Flask(name) ```

1. Define an error handler for the specific error code:python @app.errorhandler(404) def not_found_error(error): return render_template('error_404.html'), 404

2. Create an HTML template for the error page: Inside your templates folder (templates/error_404.html), you can customize the error page. For example: ```html

404 Not Found

Oops! The page you're looking for does not exist.

```

1. Run the Flask app:python if __name__ == '__main__': app.run(debug=True)

2. Testing: Access a non-existing route in your app to trigger the 404 error page and check if your custom error page displays correctly.

By following these steps, you can create a custom error page for a 404 error in Flask and tailor the content according to your requirements.
