题目：编写input()和output()函数输入，输出5个学生的数据记录。

程序分析：无。

程序源代码：

#!/usr/bin/python
# -*- coding: UTF-8 -*-

N = 3
#stu
# num : string
# name : string
# score[4]: list
student = []
for i in range(5):
    student.append(['','',[]])

def input_stu(stu):
    for i in range(N):
        stu[i][0] = raw_input('input student num:\n')
        stu[i][1] = raw_input('input student name:\n')
        for j in range(3):
            stu[i][2].append(int(raw_input('score:\n')))

def output_stu(stu):
    for i in range(N):
        print '%-6s%-10s' % ( stu[i][0],stu[i][1] )
        for j in range(3):
            print '%-8d' % stu[i][2][j]

if __name__ == '__main__':
    input_stu(student)
    print student
    output_stu(student)

以上实例输出结果为：

input student num:
2
input student name:
aaa
score:
89
score:
98
score:
67
input student num:
bbb
input student name:
ccc
score:
87
score:
45
score:
68
input student num:
ddd
input student name:
eee
score:
56
score:
78
score:
56
[['2', 'aaa', [89, 98, 67]], ['bbb', 'ccc', [87, 45, 68]], ['ddd', 'eee', [56, 78, 56]], ['', '', []], ['', '', []]]
2     aaa       
89      
98      
67      
bbb   ccc       
87      
45      
68      
ddd   eee       
56      
78      
56
