Record#

Today I learned about Object-Oriented Programming (OOP). In OOP, the first step is to create a class using the keyword class followed by the class name. When we need to use this class, we refer to it as instantiating an object.

An object itself is a template and does not have any specific meaning until it is instantiated. Subclasses can inherit information from parent classes and extend it further.

As today's assignment, I created a class called Job for use by Lawyer. Additionally, I created subclasses Teacher and Doctor which inherit information from the Job class and extend it further.

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()
