class Person(object):

    def __init__(self, name, gender, birth, **kw):

        self.name = name

        self.gender = gender

        self.birth = birth

        for t in kw:

            self.t = kw[t]

xiaoming = Person('Xiao Ming', 'Male', '1990-1-1', job='Student')

print xiaoming.name

print xiaoming.job

一定要用setattr函数？
