Python 100例题目：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：
实例
#!/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
