问题描述：对字符串排序。

源代码：

#!/usr/bin/python
# -*- coding: UTF-8 -*-
 
if __name__ == '__main__':
    str1 = raw_input('input string:\n')
    str2 = raw_input('input string:\n')
    str3 = raw_input('input string:\n')
    print str1,str2,str3
    
    if str1 > str2 : str1,str2 = str2,str1
    if str1 > str3 : str1,str3 = str3,str1
    if str2 > str3 : str2,str3 = str3,str2
 
    print 'after being sorted.'
    print str1,str2,str3

输出结果如下：

input string:
abcdefgh
input string:
efdismj
input string:
adkyt
abcdefgh efdismj adkyt
after being sorted.
abcdefgh adkyt efdismj
