类方法、静态方法

# 类方法：
class B:
    country = ‘China‘  # 静态变量（属性，字段）

    def func(self):  # 动态普通方法
        pass

    def __init__(self,name,age):  # 特殊方法：双下方法
        self.name = name

    def func2(cls):
        # print(cls)
        cls.area = ‘东北‘
        cls.name = ‘狗哥‘
print(B)
print(B.__dict__)

print(B.__dict__)

class C:
    count = 0
    def __init__(self):

    @classmethod
    def cou(cls):
