一日一技：简化数据对象的初始化方式

class Person(object):
    name = None
    age = None
    salary = None

kingname = Person()
kingname.name = 'kingname'
kingname.age = '?'
kingname.salary = 9999999

class Person2(object):
    def __init__(self, **kwargs):
        self.__dict__.update(kwargs)

kingname = Person2(name='kingname', age='?', salary=9999999)
