number = int(input("请输入学生数："))
score = {}
total = {}
i = 0
while i < number:
    no = input("请输入学号：")
    num = int(input("请输入学科数："))
    s_c = []
    for i in range(num):
        s = int(input("请输入第{}科成绩：".format(i+1)))
        s_c.append(i)
    score[no] = s_c
    total[no] = sum(s_c)
    i += 1
print(total)
