#!/usr/bin/env python

staff_list = 'user.txt'

f = open(staff_list)

c = f.readlines()

while True:

　　user_input = raw_input('33[32;1mPls input sth to search:33[0m ').strip()

　　if len(user_input) == 0: continue

　　for line in c:

　　　　if user_input in line:

　　　　　　print line

　　　　　　break

　　else:

　　　　print '33[31;1mnot a vaild input!33[0m' 

解决1次只匹配单行的问题，增加一个key，作为信号量，当匹配时则为key赋值为1，否则为0.
