class Student:

def __init__(self,name,number,score,grade):#初始化方法，定义模型

self.name=name

self.number=number

self.score=score

self.grade=grade

name=str(input())

number=str(input())

score=int(input())

grade=input()

a=Student(name,number,score,grade)#创建实例对象a，定义为Student类型，并传入具体人物资料信息

print(f"{a.name}'s student number is {a.number}, and his grade is {a.score}. He submitted {len(a.grade.split())} assignments, each with a grade of {a.grade}")#打印实例a的资料信息

########延伸另一个实例：你也可以在创建另一个实例b，传入另一个人的资料信息并打印

z=str(input())

x=str(input())

c=int(input())

v=input()

b=Student(z,x,c,v)

print(f"{b.name}'s student number is {b.number}, and his grade is {b.score}. He submitted {len(b.grade.split())} assignments, each with a grade of {b.grade}")
