    r1 = random.uniform(0, 10)

Answer 1

you'll need to issue a GET request to service 2 in order to get the random number, I suggest to use requests for this, like

r = requests.get('url-for-service-2:port/')
data = r.json()
random_num = data['message']

keep in mind to check the data object for message key, or using .get() or equivalent
