code: def get_conn(self, *args, **kwargs):
          
          connections = self.__connections_for('get_conn', args=args, kwargs=kwargs)
  
          if len(connections) is 1:
              return connections[0]
          else:
              return connections
docs: Returns a connection object from the router given ``args``.
  
          Useful in cases where a connection cannot be automatically determined
          during all steps of the process. An example of this would be
          Redis pipelines.
