Async / Await usage with asyncio to retrieve urls in parallel

[mlieqo]

1.) yes good point, you definitely don't want to create a session per request, so in this case you can just move the context manager in the gather_coro and pass it as a argument to get_url_result function:

def get_results(urls):

  async def gather_coro():
    async with aiohttp.ClientSession() as session:   # moved here from get_url_result
      return await asyncio.gather(*(get_url_result(url, session) for url in urls))

  url_results = asyncio.run(gather_coro())
  return dict(url_results)

2.) Yes, get_url_result can return just resp, creation of dictionary really shouldn't be a problem! But remember that in order to access response content like resp.text() you need to await it, this means you won't be able to access it from a normal function but only from coroutine, from docs -

aiohttp loads only the headers when .get() is executed, letting you decide to pay the cost of loading the body afterward, in a second asynchronous operation. Hence the await response.text().
