Python--实例变量

class Person(object):
    country = 'China'  # 类变量

    def __init__(self, name, age, sex):
        self.name = name  # 实例变量，必须实例化才能用，也叫成员变量
        self.age = age
        self.sex = sex

    def say_my_country(self):
        print(self.country)


# dsx = Person('大师兄', 23, '男')
# print(dsx.name)
# print(dsx.age)
# print(dsx.sex)
# print(dsx.country)
# ds = Person('原宝清', 28, '男')
print(Person.country)
