Python3调用百度翻译API，实现实时翻译

今天需要做一个翻译的工具，找到之前写过的有道翻译，已经不能用了，最后看到百度翻译还不错，不过官方版本是Python2，我需要Python3，就自己写了一个：

# coding: utf8

    说明： appid和secretKey为百度翻译文档中自带的，需要切换为自己的
           python2和python3部分库名称更改对应如下：
           httplib      ---->    http.client
           md5          ---->    hashlib.md5
           urllib.quote ---->    urllib.parse.quote
