#案例

class Student():

    def __init__(self,name,age):

        self.name=name

        self.age=age

    def __str__(self):

        return self.name

student=Student('xiaodeng',28)

print student                   #xiaodeng

print student.name              #xiaodeng

print student.age               #

#setattr

setattr(student,'set','')

print student.__dict__          #{'age': 28, 'set': '1', 'name': 'xiaodeng'}

#__setattr__;通常在class中运用较多
