title: Python periodically refresh data from OWM
body: <p>i built simple weather app using Kivy and OWM, but i ran into a problem. while program works fine, i got stuck on the way to reload (get again) data from OWM. I´ve tried <code>time.sleep()</code> but then i dont know how to remain app open. I didn´t find anything on internet, i tried googling but everything i could find was just event handling action. My guess is to use some sort of timer set to 2 minutes to call that function, but then how do i refresh Kivy app? So i want just the "<code>owm.get_weather()</code>" to be run every 2 minutes or so. Hope you understood. Thanks for help :) 
  P.S. i forgot my code.. <a href="https://github.com/ApplePie420/OWMapp/blob/master/main.py" rel="nofollow noreferrer">https://github.com/ApplePie420/OWMapp/blob/master/main.py</a></p>
