code: def latencies(self):
          
          return [(shard_id, shard.ws.latency) for shard_id, shard in self.shards.items()]
docs: List[Tuple[:class:`int`, :class:`float`]]: A list of latencies between a HEARTBEAT and a HEARTBEAT_ACK in seconds.
  
          This returns a list of tuples with elements ``(shard_id, latency)``.
