Web App That Request Data from Another Web Site every 12-hours

[jomonetta]

Hi, I am working on a web app with flask framework. I want to get a data from another web site every 12 hour, save it and display it through my web app, but what should I do? I can get the data from another web site with requests package but what I want is done this every 12 hour and display it through my web app users while the app is online.
