上面列出了我得到的 url 示例.我想知道 Python 中是否有任何模块可以用来解析用户代理.我想从这些示例中获取输出，例如:

The samples of the urls I've got are listed above. I am wondering if there is any module in Python which I can use to parse the user-agent. I want to get the output from these samples like:

Android
HTC Streaming player
ipad

如果是PC用户，我想获取网络浏览器类型.

and if it is a PC user, I want to get the web browser type.

推荐答案

有一个库叫做 httpagentparser 为此:

There is a library called httpagentparser for that:

import httpagentparser
>>> s = "Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/532.9 (KHTML, like Gecko) Chrome/5.0.307.11 Safari/532.9"
>>> print httpagentparser.simple_detect(s)
('Linux', 'Chrome 5.0.307.11')
>>> print httpagentparser.detect(s)
{'os': {'name': 'Linux'},
 'browser': {'version': '5.0.307.11', 'name': 'Chrome'}}
