Python物件導向OOP
物件(Object)是類別(Class)的實例(Instonce)
ex: 車子 => 類別Class,每一台生產出來的車子 =>物件Object
類別提供藍圖能初始化製造物件，利用初始化給物件屬性及定義
創建物件個屬性

class Car:
    def __init__(self, make, model, year, color):
    #初始化
       self.make = make
       self.modle = modle
       self.year = year
       self.color = color
car1 = Car("Toyota", "Altis", 2021, "blue")
Car2 = Car("Ford", "Kuga", 2020, "black")
print(car1, make)
print(car1, modle)
print(car1, year)
print(car1, color)


Toyota
Altis
2021
blue

創建物件功能函式

class Car:
    def __init__(self, make, model, year, color):
    #初始化
       self.make = make
       self.modle = modle
       self.year = year
       self.color = color
   def drive(slef):
       print(self.modle + "正在行駛")
   def stop(self):
       print(self.modle + "已停止")
    
car1 = Car("Toyota", "Altis", 2021, "blue")
Car2 = Car("Ford", "Kuga", 2020, "black")

car1 drive()
car2 drive()
car1 stop()


Altis正在行駛
Kuga正在行駛
Altis已停止

類別變數

class Car:
    wheels = 4
    #因所有類別都為此變數，可直接宣告
    def __init__(self, make, model, year, color):
    #初始化
       self.make = make
       self.modle = modle
       self.year = year
       self.color = color

Car1 = Car("Ford", "Focus", 2023, "gray")
print(car1, wheels)

#機車
Car2 = Car("Gogoro", "CrossOver", 2024, "gray")
print(car2.models)
car2.wheels = 2
print(car2.wheels)


4
CrossOver
2
