今天我学习了面向对象编程（OOP）。在面向对象编程中，首先需要创建一个类，使用关键字class后面跟着类名。当我们需要使用这个类的时候，我们称之为实例化对象。

对象本身是一个模板，没有具体的运行意义。只有在实例化之后，对象才具有具体的价值。子类可以继承父类的信息，并且在此基础上进行扩展。

作为今天的作业，我创建了一个名为Job的类，供Lawyer调用。同时，我还创建了Teacher和Doctor子类，它们继承了Job类的信息，并在此基础上进行了扩展。

CODE#

class job:
  name = None
  salary = None
  hours = None

  def __init__(self, name, salary, hours):
    self.name = name
    self.salary = salary
    self.hours = hours

  def print(self):
    print(f"{self.name} > {self.salary} > {self.hours}")


class doctor(job):
  speciality = None
  years = None

  def __init__(self, name, salary, hours, speciality, years):
    self.name = name
    self.salary = salary
    self.hours = hours
    self.speciality = speciality
    self.years = years

  def print(self):
    print(
      f"{self.name} > {self.salary} > {self.hours} > {self.speciality} > {self.years}"
    )


class teacher(job):
  subject = None
  position = None

  def __init__(self, name, salary, hours, subject, position):
    self.name = name
    self.salary = salary
    self.hours = hours
    self.subject = subject
    self.position = position

  def print(self):
    print(
      f"{self.name} > {self.salary} > {self.hours} > {self.subject} > {self.position}"
    )


laywer = job("张三", "1万", "8小时")
doctor1 = doctor("李四", "2万", "9小时", "儿科", "十年")
teacher1 = teacher("王五", "3万", "10小时", "计算机", "教授")

laywer.print()
doctor1.print()
teacher1.print()
