最近在写流量监控，需要分析 User Agent，写了两行，放弃，我为什么不找个工具干这事。
user_agents 是 Python 库，可以解析用户代理中使用系统、设备、浏览器等信息。它依赖于 ua_parse 解析库对原始代理字符串的解析。
下载
1 | pip install pyyaml ua-parser user-agents |

# Accessing user agent's operating system properties
user_agent.os # returns OperatingSystem(family=u'iOS', version=(5, 1), version_string='5.1')
user_agent.os.family # returns 'iOS'
