title: python list_objects() only accepts keyword arguments
body: <p>I have created the following loop which obtains the path to certificates <code>CERTIFICATION_PATH</code>. It is made up of the path: bucket/organisation/uuid</p>
  <pre><code>import json
  import boto3
  
  for data in json_data:
      MQTT_TOPIC = &quot;{organisation}/{device_vendor}/{device_type}&quot;.format(**data)
      CERTIFICATION_PATH = &quot;{}/{organisation}/{uuid}&quot;.format(bucket, **data)
      
  for uuid_index, uuid in enumerate(uuid_list): 
      result = client.list_objects(CERTIFICATION_PATH)
      print('-------------------')
      print(result)
      print('-------------------')
  </code></pre>
  <p>I'm getting the error <code>list_objects() only accepts keyword arguments.</code> when I do the above. Is there another way to list the objects in the <code>CERITIFCATION_PATH</code></p>
