title: Get aiohttp request response in callback with a infinite loop of asyncio task
body: <p><strong>What I am doing</strong>- I am trying to make multiple post requests(to the same URL with different parameters) in an infinite loop using asyncio and aiohttp. </p>
  
  <pre><code>def callback(response):
      print(response) 
  
  async def make_request(session, payload, sema):
          async with sema, session.post(url=URL, headers=HEADERS, data=json.dumps(payload)) \
                  as response:
              return await response.json()
  
  
  async def generate_requests(payloads):
      tasks = []
      sema = asyncio.BoundedSemaphore(value=100)
      async with aiohttp.ClientSession() as session:
          for payload in payloads:
              tasks.append(make_request(session, payload, sema))
          results = await asyncio.gather(*tasks, return_exceptions=True)
          print(results)
  
  
  def run_asyncio_requests():
      loop = asyncio.get_event_loop()
      while True:
          for country in countries:
              cities = country.cities
              loop.run_until_complete(generate_requests(cities))
  
  
  if __name__ == '__main__':
      run_asyncio_requests()
  </code></pre>
  
  <p><strong>Problem:</strong> <em>run_asyncio_requests</em> function generates and make multiple requests(cities against a country) and then await for all responses for one country requests then executes the next country requests. </p>
  
  <p><strong>What I want:</strong> All countries' requests should be executed at once and callback(some kind of linked function with each request) function should handle each response because post request response time for each request is different. It should not wait to gather all the responses. Requests should be generated in each cycle(infinite-loop) and callback function in the background should be linked with each response. I know I am using <em>asyncio.gather</em> to get all responses until requests completed. But I have no idea how to do that.</p>
