python中类的定义

class Person(object):

    shool = '丰华中学'  #全局变量

    def __init__(self,name,person_age):
        self.name = name
        self.age = person_age

    def sayHi(self):
        print('Hello,my name is %s,I am %s years old' % (self.name,self.age))
        print('我的学校是%s' % self.shool)

    def __str__(self):
        return 'name: %s, age: %s' % (self.name,self.age)

if __name__ == '__main__':      #当该文件被当成模块调用时，不执行该main函数
    p =  Person('Tom',32)
    p.sayHi()
    print(p)
