python自定义类

设计一个Person类的3种方式：
1、使用内建类型list
person=[‘mike’, 23, ‘male’] #0-姓名, 1-年纪, 2-性别
print(person[0], person[1], person[2])

2、使用字典类型dic
person1={‘name’:‘mike’, ‘age’: 23, ‘sex’: ‘male’}
person2={‘name’:‘hellen’, ‘age’: 20, ‘sex’: ‘female’}
print(person1[‘name’], person1[‘age’], person1[‘sex’])

3、使用自定义类

class Person:

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

        self.name = name

        self.age = age

        self.sex = sex

    def __str__(self): #重载该函数便于测试

        sep = ','

        return self.name+sep+str(self.age)+sep+self.sex

person1 = Person('mike', 23, 'male') 

person2 = Person('hellen', 20, 'female')

print(person1)

print(person2.name, person2.age, person2.sex)
