How can you "put to sleep" the application?

Question

Python

I have a similar script:

....
while 1:
    count = requests,post(url, data=data).json()['count']
    print('[i] Count: {0}".format(count))
    time.sleep(60*60) # 1 hour

On heroku, the program is unstable. She sometimes may not show this value.
What to do?
