標籤:證明   面向   gpo   擴充   int   插入   eating   nbsp   一個   

小結主要講述物件導向的優點,可擴充性高

範例程式碼如下:

 1 class Chinese: 2     def __init__(self,name,age,sex): 3         self.name=name 4         self.age=age 5         self.sex=sex 6  7  8 p1 = Chinese(‘egon‘,18,‘male‘) 9 p2 = Chinese(‘alex‘,38,‘female‘)10 p3 = Chinese(‘wpq‘,48,‘female‘)

我們往類中插入一個資料屬性,只需在類中添加即可,對象不需做什麼改動就可以訪問,代碼驗證如下:

 1 class Chinese: 2     country = ‘China‘ 3     def __init__(self,name,age,sex): 4         self.name=name 5         self.age=age 6         self.sex=sex 7  8  9 p1 = Chinese(‘egon‘,18,‘male‘)10 p2 = Chinese(‘alex‘,38,‘female‘)11 p3 = Chinese(‘wpq‘,48,‘female‘)12 13 print(p1.country)14 print(p2.country)15 print(p3.country)

結果如下:

China
China
China 證明都可以訪問

插入一個函數屬性,只需在類中添加即可,對象不需做什麼改動就可以訪問,代碼驗證如下:

 1 class Chinese: 2     country = ‘China‘ 3     def __init__(self,name,age,sex): 4         self.name=name 5         self.age=age 6         self.sex=sex 7  8     def eat(self): 9         print(‘%s is eating‘ % self.name)10 11 12 p1 = Chinese(‘egon‘,18,‘male‘)13 p2 = Chinese(‘alex‘,38,‘female‘)14 p3 = Chinese(‘wpq‘,48,‘female‘)15 16 p1.eat()17 p2.eat()18 p3.eat()

結果如下:

egon is eating
alex is eating
wpq is eating
