python创建对象和一些基本用法：

class Student(object):
    myname="Studnet"
    def __init__(self, name, score):
        self.__name = name
        self.__score = score

    def print_score(self):
        print('%s: %s' % (self.__name, self.__score))

    def get_name(self):
        return self.__name

    def get_score(self):
        return self.__score

    def set_score(self, score):
        self.__score = score
if __name__ == '__main__':
    bart = Student('Bart Simpson', 59)
    bart.print_score()
    print(bart.myname,Student.myname)
    print(type(bart))
    print(type(123)==int)
输出：

Bart Simpson: 59
Studnet Studnet
<class '__main__.Student'>
True
