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.
