如何在python中继承另一个类的属性

这里有一个例子

class Person():
  def __init__(self, name, age):
    self.name = name
    self.age = age

  def getName(self):
    return self.name
  def getAge(self):
    return self.age


class Student(Person):
  def __init__(self, name, age, id):
    self.id = id
    super().__init__(name, age)

  def getId(self):
    return self.id

new_student = Student('Student', 20, 666)

print(new_student.getName())

关于你的具体情况:

class Info(object):
    def __init__(self, slot_number, board_type, board_part_num, prod_part_num):
        self.slot_number = slot_number
        self.board_type = board_type
        self.board_part_num = board_part_num
        self.prod_part_num = prod_part_num

     def getSlotNumber():
          return self.slot_number

class Connection(Info):
    def __init__(self, system, sn, phase, ip, port, slot_number, board_type, board_part_num, prod_part_num):
        super().__init__(slot_number, board_type, board_part_num, prod_part_num)
        self.system = system
        self.sn = sn
        self.slot_number = slot_number
        self.phase = phase
        self.ip = ip
        self.port = port

你可以通过创建get方法来访问Info的属性。

new_connection = Connection('system', 'phase', 'ip', 'port', 'slot_number', 'board_type', 'board_part_num', 'prod_part_num')
new_connection.getSlotNumber()
