Flux ask is a flask extension. It's made by the sky john wheeler, and it's a really cool tython package to get started with. You just have your view function, and when you return your response, it provides special response classes to either ask or tell the user. So you can ike, ask something and then expect response back to that question, or you can just send a message to the user. And i've seen that it's pretty cool. A lot of people in no flask, or they know some python web framework, super similar flask, and away another.
