如何用super构造类实例?

class TravellingSalesmanProblem(Annealer):

    """Test annealer with a travelling salesman problem.
    """

    # pass extra data (the distance matrix) into the constructor
    def __init__(self, state, distance_matrix):
        self.distance_matrix = distance_matrix
        super(TravellingSalesmanProblem, self).__init__(state)  # important!

克隆自 simanneal

def __init__(self, state, distance_matrix):
    self.state = state
    super(TravellingSalesmanProblem, self).__init__(distant_matrix)

这就是一个职业运动员的样子

class Annealer(object):
       __metaclass__ = abc.ABCMeta

    # defaults
    Tmax = 25000.0
    Tmin = 2.5
    steps = 50000
    updates = 100
    copy_strategy = 'deepcopy'
    user_exit = False
    save_state_on_exit = False

    # placeholders
    best_state = None
    best_energy = None
    start = None

    def __init__(self, initial_state=None, load_state=None):
        if initial_state is not None:
            self.state = self.copy_state(initial_state)
        elif load_state:
            self.load_state(load_state)
        else:
            raise ValueError('No valid values supplied for neither \
            initial_state nor load_state')

        signal.signal(signal.SIGINT, self.set_user_exit)

它也有很多其他的方法,但是那会占用太多的空间。
