Python类属性报错AttributeError : can't set attribute

Question

class DockerEngine(Device):

  def __init__(self):
      super(DockerInfo, self).__init__()
      self.docker_id = None
      self.host_ip_address = None
      self.total_containers = 0
      self.running_containers = 0
      self.paused_containers = 0
      self.stopped_containers = 0

  @property
  def host_ip_address(self):
      return self._host_ip_address

  @host_ip_address.setter
  def host_it_address(self, ip):
      self._host_ip_address = ip

  @property
  def docker_id(self):
      return self._docker_id

  @docker_id.setter
  def docker_id(self, id):
      self._docker_id = id

当我初始化一个 DockerEngine 对象时，它提示说在 __init__ self.host_ip_address 中，无法设置属性。

你的代码有错字

将host_it_address更改为host_ip_address.

@host_ip_address.setter
def host_it_address(self, ip): <--- WRONG FUNCTION NAME
    self._host_ip_address = ip
