How to display in a div what arduino writes to the port in real time?

Question

Python

Good afternoon.
I can't figure out how to use tornado to output the values ​​given by arduino in real time to a certain div.
Please provide a link to a simple example.

Answer 1

Smoke the theme of websockets, or you can pull from the server with a simple ajax request on timeout (in this case, the tornado is really redundant, you can get by with the flask)
