Perform a function at a regular time-based interval with python

Question

I'm currently trying to retrieve the contents of a webpage (JSON) that updates very regularly. Ideally, I would like to download the data from this URL every 10 minutes and save it, appending it to a growing data structure of updates.

Is there a way to repeatedly run a python function at a user-defined interval (10 minutes)?

In my case, I'm able to download a url using the below code, but wish to add data to it every 10 minutes.

with urllib.request.urlopen(URL) as url:
data = json.loads(url.read().decode())
print(data)

Yes, one way is you can use "Cron" https://en.wikipedia.org/wiki/Cron — Amit Tripathi, Dec 02 '17 at 07:40

This is a very poor answer; you should improve it by providing better explanation on how to precisely use crontab for this case. – Reblochon Masque Dec 02 '17 at 07:48
