我无法理解将对象作为参数传递的情况

Question

我有一个带有定义函数的类Node

class Node(object):
    def __init__(self, index, state = None, input = None, directed_neighbours=False):
       """
       Parameters
       ----------
       index : int
        Node index. Must be unique in the graph.
       """
       self._input = input
       self.state = state
       #self._status = 'active'
       self._index = int(index)
       self._neighbours = set()
       self._port_count = 0
       self._ports = []
       if directed_neighbours:
           self._predecessors = set()
           self._successors = self._neighbours
           self._directed_neighbours = True
       else:
           self._successors = self._neighbours
           self._predecessors = self._neighbours
           self._directed_neighbours = False

    @property
    def setStatus(self, status):
        self._status = status

我还有另一个功能

def init(node):
    node.setStatus('active')

现在，我有一堂课

class DistAlgo:

     def __init__(self, name, initFunc, states, messages, sendFunc, receiveFunc, stoppingCheck):
        self.name = name
        #self.inputGraph = inputGraph
        self.initFunc = initFunc
        self.states = states
        self.messages = messages
        self.sendFunc = sendFunc
        self.receiveFunc = receiveFunc
        self.comm_round = 0
        self.stoppingCheck = stoppingCheck

    def run(self, inputGraph):

        for node in inputGraph.nodes:
            print('hello', node)
            node.state = self.initFunc(node)
        <....more code...>

当我创建DistAlgo的对象时

myalgo = DistAlgo('BMM', init, states, messages, send, receive, stoppingCheck)

然后调用其运行功能：

myalgo.run(problemGraph)

我在上面的init函数中遇到错误，如下所示：

TypeError: setStatus() missing 1 required positional argument: 'status'

我肯定做错了很多事情，因为这是我第一次尝试Python。 请指出来！

属性的工作方式略有不同：

@property
def status(self):
    return self._status

@status.setter
def status(self, status):
    self._status = status

现在，您可以通过分配来设置值：

node.status = 'active'
