title: Python EST API Multi Thread from List
body: <p>I've got a Python list of ~380 records I need to send to an API but it's slow doing it individually.  I currently can use this:</p>
  
  <pre><code>payload_length = len(payload)
  for i in range(0, payload_length):
      send_contacts(payload[i])
  </code></pre>
  
  <p>To send an individual contacts but wondered if I could start x number of threads.  I read about asynchronous request and grequests but I can't get my head around the code.</p>
  
  <p>I'd be grateful of any pointers.</p>
