How to fetch updated JSON data continuously using python

Question

While working with json in python, I've written this small script to fetch the current price of BTC. This works fine when I run the script in Ubuntu terminal.

What I want is to update the variable current_price for every minute so that I can use this variable to display a desktop notification for current price.

I was looking for cron to schedule the task but It'll not work because I want to run the script after each minute, not at a specific time.

what is the best practice to achieve this?

import urllib, json

url = "https://koinex.in/api/ticker"
response = urllib.urlopen(url)
data = json.loads(response.read())

current_price = data["prices"]["BTC"]

print current_price

You can set up `cron` to run every minute: https://stackoverflow.com/questions/5398014/using-crontab-to-execute-script-every-minute-and-another-every-24-hours — r.ook, Jan 24 '18 at 07:17

To run the script every minute you can use cron job:

EX:

* * * * * python /PATH_TO_SCRIPT/script.py

I've added the job in cron tab. * * * * * python ~/price.py How do I know if the job is working? Will a new terminal popup each minute with the value of current_price ? – Srideep Nayak Jan 24 '18 at 09:22
You add a logging function inside the script to check it – Rakesh Jan 24 '18 at 09:24
Working fine! Thanks a ton Rakesh – Srideep Nayak Jan 24 '18 at 10:04
