关于继承/多重继承中的参数传递

class Service(object):    def __init__(self, host, binary, topic, manager, report_interval=None,             periodic_interval=None, *args, **kwargs):        print 'Initializing Service'print kwargsprint args        super(Service, self).__init__(*args, **kwargs)        print 'Service: ' + binary, args, kwargsclass Color(object):    def __init__(self, color='red', **kwargs):        print 'Initializing Color'        self.color = colorprint kwargs        super(Color, self).__init__(**kwargs)        print 'Color: ', kwargsclass ColoredService(Service, Color):    def __init__(self, *args, **kwds):        print 'Initializing Colored Service'        super(ColoredService, self).__init__(*args, **kwds)c = ColoredService('host', 'bin', 'top', 'mgr', 'ivl', color='blue')

输入结果如下所示：
