改编自:http://www.oschina.net/code/snippet_70229_2366  加了终端颜色罢了

效果:

code:

#!/usr/bin/env python2
#coding=utf-8

import urllib,sys,re

#预编译正则式
re_def =re.compile(r'<def>(.*?)</def>', re.M|re.I|re.S|re.U)
re_sugg=re.compile(r'<sugg>(.*?)</sugg>', re.M|re.I|re.S|re.U)
re_orig=re.compile(r'<orig>(.*?)</orig>', re.M|re.I|re.S|re.U)
re_tran=re.compile(r'<trans>(.*?)</trans>', re.M|re.I|re.S|re.U)
#终端颜色
WARNING='\033[93m'
OKBLUE='\033[94m'
OKGREEN='\033[92m'
END = '\033[0m'
#是否输出例句
eg=True

    return s.replace('&lt;em&gt;',OKGREEN).replace('&lt;/em&gt;',END)
