person類中的OBJECT 是必須的， 否則報(bào)錯(cuò)?

請給 Animal類添加一個(gè)類屬性 count，每創(chuàng)建一個(gè)實(shí)例，count 屬性就加 1，這樣就可以統(tǒng)計(jì)出一共創(chuàng)建了多少個(gè) Animal的實(shí)例。

#?Enter?a?code
class?Animal(object):
????count?=?0
????def?__init__(self,?name,?age):
????????Animal.count?+=?1
????????self.name?=?name
????????self.age?=?age
dog?=?Animal('xiaohuang',?5)
cat?=?Animal('mimi',?3)
print?Animal.count

##類屬性也是可以動態(tài)添加和修改的，需要注意的是，因?yàn)轭悓傩灾挥幸环?/p>

class person():

? ? _location = 'aisa'

? ? def __init__ (self,name,age):

? ? ? ? self.name = name

? ? ? ? self.age = age

? ? def set_location(cls,location):

? ? ? ? cls._location = location

? ? def get_location(cls):

? ? ? ? return cls._location

p = person('wabgwabg',16)

p.set_location('qwe111')

print p._location

xl = p.get_location()

print xl

class person():

? ? def __init__(self,name,age):

? ? ? ? self.name = name

? ? ? ? self.age = age

? ? def get_name(self):

? ? ? ? return self.name,self.age

? ? ? ??

p= person('wangwang',15)

xm = p.get_name()

print('name={}','age={}'.format(xm[1],xm[0]))

tuple list 為什么是讀取不成功， 重新看下? tuple 與list。

class Animal(object):

? ? def __init__(self, name, age):

? ? ? ? self.name = name

? ? ? ? self._age = age

cat = Animal('Kitty', '3')

print(cat.name)

print(cat._age)

class person():

? ? def __init__(self,name,sex,age):

# two_ befor and behind init

? ? ? ? self.name = name

? ? ? ? self.sex = sex

? ? ? ? self.age = age

xm = person('name','s',15)

print xm.name

class animal():pass

dog = animal()

cat = animal()

dog.name ='wangwang'

cat.name ='miaomiao'

dog.age =4

cat.age =2

print dog.name

print cat.age

__count的意思是把count改為私有，實(shí)例、類都無法直接在def外部訪問__count，是倆橫線。報(bào)錯(cuò)為沒有__count這個(gè)屬性。

Animal.count+=1

是Animal.count=Animal.count+1的意思
