因为有道翻译有反爬虫机制，所以简单的爬肯定不行，修改一下url，去掉_o

现在的url：http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule
原来的url：http://fanyi.youdao.com/translate_o?smartresult=dict&smartresult=rule　　

附上重要代码讲解

请输入翻译的内容:jia
                          {"type":"EN2ZH_CN","errorCode":0,"elapsedTime":2,"translateResult":[[{"src":"jia","tgt":"贾"}]]}

>>> target = json.loads(html)
>>> target[\'translateResult\'][0][0]
{\'src\': \'jia\', \'tgt\': \'贾\'}
>>> target[\'translateResult\'][0][0][\'tgt\']
\'贾\'
