代碼如下：

class Animal(object):

? ? __localtion = 'Asia'

? ? __count = 1

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

? ? ? ? self.name = name

? ? ? ? self.age = age

? ? ? ? Animal.__count += 1

? ? @classmethod

? ? def get_count(cls):

? ? ? ? return cls.__count

dog = Animal('wangwang', 1)

cat = Animal('mimi', 3)

pig = Animal('panpan', 1)

print(Aniaml.get_count())

報(bào)錯(cuò)如下：

Traceback?(most?recent?call?last):
??File?"index.py",?line?17,?in?
????count?=?Aniaml.get_count()
NameError:?name?'Aniaml'?is?not?defined
