use of @attr in python inside a class

Question

I am going through open-stack Tempest code. I see some syntax @ used inside a class as below. Could some one give me a proper link where i can learn above why this @ is used.

  @classmethod
      def setUpClass(cls):
      cls.set_network_resources()
      super(TestLargeOpsScenario, cls).setUpClass()

or even like this,

  @attr(type='smoke')
  def test_update_setver_name(self):
        name = rand_server('server')

so what is the use of @ over here?

There are decorators. Loads of article available on it. http://legacy.python.org/dev/peps/pep-0318/ — rajpy, Aug 27 '14 at 06:54
