Sync, using requests: import requests def main(): with requests.Session() as s: r = s.get('https://...') result = r.json() main() Async, using aiohttp: import aiohttp import asyncio async def main(): async with aiohttp.ClientSession() as s: async with s.get('https://...') as r: result = await r.json() loop = asyncio.get_event_loop() loop.run_until_complete(main()) If you're making many HTTP requests, you can use async, queue them up and it greatly improves performance.
