为什么打印出来不是函数方法定义的格式呢？打印出来是（‘xiaoming’,'Male',90）

class Student(object):

    def __init__(self, name, gender, score):

        self.name = name

        self.gender = gender

        self.score = score

    def __str__(self):

        return 'name is {}, gender is {}, score is {}'.format(self.name, self.gender, self.score)

    def __repr__(self):

        return 'name is {}, gender is {}, score is {}'.format(self.name, self.gender, self.score)

s = ('xiaoming','Male',90)

print(s)
