OOP - 64天 - 在線學python100天

記錄#

今天我學習了面向對象編程（OOP）。在面向對象編程中，首先需要創建一個類，使用關鍵字class後面跟著類名。當我們需要使用這個類的時候，我們稱之為實例化對象。

對象本身是一個模板，沒有具體的運行意義。只有在實例化之後，對象才具有具體的價值。子類可以繼承父類的信息，並且在此基礎上進行擴展。

作為今天的作業，我創建了一個名為Job的類，供Lawyer調用。同時，我還創建了Teacher和Doctor子類，它們繼承了Job類的信息，並在此基礎上進行了擴展。

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("張三", "1萬", "8小時")
doctor1 = doctor("李四", "2萬", "9小時", "兒科", "十年")
teacher1 = teacher("王五", "3萬", "10小時", "計算機", "教授")

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