How can I create custom error pages in Flask?

You can create custom error pages in Flask by defining error handlers for specific HTTP status codes. Would you like an example?

Yes, please provide an example for a 404 error page.

Sure! You can use the @app.errorhandler(404) decorator to define a function that returns your custom 404 page. Here's a simple example:

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

What if I want to customize other error pages like 500?

You can do that similarly by using @app.errorhandler(500) for internal server errors. Just create a function that returns your custom 500 page.
