類
- 類名
- 屬性
- 方法
class 類名:
方法列表
- 定義一個(gè)類:
- ==在類中定義的方法澎语，第一個(gè)參數(shù)都要寫(xiě)self==
class Dog:
def bark(self):
print('wang wang ~')
- 創(chuàng)建一個(gè)對(duì)象
dog = Dog()
dog.bark()
- 添加屬性
dog = Dog()
dog.weight = 5
dog.color = 'yellow'
- 獲取屬性
print(dog.weight)
- 在方法中修改屬性
class Cat:
def eat(self):
print('吃魚(yú)')
self.weight += 1
- 直接修改屬性
cat = Cat()
cat.weight = 1o
cat.eat()
cat.weight += 5
print(cat.weight)
- __init__方法
- ==創(chuàng)建對(duì)象的時(shí)候自動(dòng)執(zhí)行薄啥，類似于構(gòu)造方法==
class Dog:
def __init__(slef):
self.weight = 5;
self.color='yellow'
class Cat:
def __init__(self,weight,color):
self.weight = weight
self.color = color
- self
- ==程序中必須使用self疯攒，不然程序會(huì)崩潰==
