Creating Subscriptions with multiple attachments using REST API

Creating Subscriptions with multiple attachments using REST API
Since Strategy 2021 it is possible to use REST API to create subscriptions. Even better, it is possible to add multiple attachments to such subscriptions. This is a long anticipated improvement to the platform.
Python script below is based on plain string format of request body. It is also possible to use just mstrio module (mstrio 11.3 !) which should further simplify the script. More details about mstrio.admin.subscription package you can find here: https://www2.Strategy.com/producthelp/2020/mstrio-py/mstrio.admin.subscription.html
Please note - I've added color formatting in the code below (http://hilite.me/). Code copied from here might not work due to indentation issues. In that case, use attached file with sample code.

from datetime import datetime
from mstrio.connection import Connection
 
#### Parameters ####
api_login = 'administrator'
api_password = ''
base_url = 'http ://MSTR-SERVER/MicroStrategyLibrary/'
project_id = 'B7CA92F04B9FAE8D941C3E9B7E0CD754'

### FUNCTIONS
def postSubscription(connection, project_id, headers, data):
    r = connection.session.post(url=connection.base_url + "/api/subscriptions", headers=headers, data=data)
    if r.ok:
        print("Error: " + str(r.raise_for_status()) + "   ||   HTTP Status Code: " + str(r.status_code))
    else:
        print("HTTP %i - %s, Message %s" % (r.status_code, r.reason, r.text))

### REST Parameters
headers = {"X-MSTR-ProjectID" : project_id,
           'Content-Type':'application/json','Accept':'application/json'}
