class?Person(object):
????def?__init__(self,?name,?gender):
????????????self.name?=?name
????????????self.gender?=?gender
class?Student(Person):
????def?__init__(self,?name,?gender,?score):
????????????super(Student,?self).__init__(name,?gender)????????
????????????self.score?=?score????
????def?__str__(self):
????????????return?'(Student:%s,%s,%s)'%(self.name,self.gender,self.score)
????__repr__=__str__

s?=?Student('Bob',?'male',?88)
print?s

沒問題呀，你看下是不是輸入法的問題哦
