在ubuntu下每次想翻译一个词或者一句话都要开浏览器上google翻译，感觉挺麻烦。于是自己写了一个python小脚本（googleTranslate.py），简化这个流程。

#!/usr/bin/python
# coding=utf-8

import urllib,urllib2
import sys
if __name__ == '__main__':
    if len(sys.argv) < 2:
        exit()
    tolanguage = 'en'
    text = ""
    if sys.argv[1] == 'en':
        tolanguage = 'en'
    elif sys.argv[1] == 'ch':
        tolanguage = 'zh-CN'
    else:
        text = sys.argv[1]
    for i in range(2, len(sys.argv)):
        text += sys.argv[i] + " "
    values = {'client':'t', 'text': text, 'hl':'en', 'sl':'auto', 'tl':tolanguage, 'ie':'UTF-8', 'oe':'UTF-8', 'multires':'1', 'otf':'2', 'ssel':'0', 'tsel':'0', 'sc':'1'}
    url = 'http://translate.google.cn/translate_a/t'
    request = urllib2.Request(url, urllib.urlencode(values))
    request.add_header('User-Agent', "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.79 Safari/537.4")
    response = urllib2.urlopen(request)
    data = response.read()
    #print data
    frags = data[4:data.find("]]")].split("\"],[\"")
    totext = ""
    for frag in frags:
        totext += frag.split("\",\"")[0]
    print totext

将这个脚本放在某个目录下，此处以/path/to为例子。使用以下命令添加脚本可执行属性

chmod +x googleTranslate.py

然后在.bashrc最后添加一行

alias t='/path/to/googleTranslate.py'

于是乎在任何界面下想要翻译词句子，直接ctrl+alt+t，输入

t 想要翻译的词句

即可。默认是将词句翻译成英文，如果需要将其他语言翻译成中文，执行

t ch 想要翻译的词句

即可。方便快捷，o(∩∩)o...哈哈

而后觉得写成一个小软件还是很靠谱的，于是又折腾了下python Tkinter，把上面的代码加了一个GUI的外壳。废话少说，上图

GUI的代码也不复杂，顺便也贴了吧，供大家交流。BUG比较多，有待后期改进，谢谢阅读！
