TypeError

[deanhystad]

The example.py for pihole shows it used this way:

import asyncio
import json
import aiohttp
from pihole import PiHole

async def main():
    """Get the data from a Pi-hole instance."""
    async with aiohttp.ClientSession() as session:
        data = PiHole('192.168.0.215', loop, session)
        await data.get_data()

        # Get the raw data
        print(json.dumps(data.data, indent=4, sort_keys=True))
        print("Status:", data.status)
        print("Domains being blocked:", data.domains_being_blocked)

loop = asyncio.get_event_loop()
loop.run_until_complete(main())

Where is your loop and session?
