python编程基础及应用（重庆大学）：9-8 设计一个学生类

编写程序，设计一个学生类。包含姓名，学号及计数器三个属性，其中计数器属性用来统计实例化了多少个学生

#井号后的内容皆可不要
class Student:
    count=0     #类的计数属性
    def __init__(self,name,id):
        self.name=name
        self.id=id
        # self.Emotionalstate=""
        # self.qqnum=""
        # self.appearance=""
        # self.height=""
        # self.weight=""
        # self.age=""
        Student.count = Student.count + 1
    # def description(self):
    #     print("{0}是一个{1}的女孩，身高{2}cm，年龄{3}岁，体重{4}kg，目前感情状况{5}，联系方式{6}，冲冲冲！".
    #           format(self.name,self.appearance,self.height,self.age,self.weight,self.Emotionalstate,self.qqnum))

if __name__=="__main__":
    student1=Student("tutu","2020440001")
    #=============================================================#
    # student1.age="20"
    # student1.weight="45"
    # student1.Emotionalstate="single"
    # student1.appearance="pretty"
    # student1.height="155"
    # student1.qqnum="2117472285"
    # student1.description()
    #=============================================================#
    student2=Student("fanfan","2020440002")
    student3=Student("huanhuan","2020440003")
    print("已经实例化：",Student.count,"个学生")
")

运行结果：
