python解析浏览器UA

一个非常神奇的包可以帮助我们优雅的解析浏览器的UA，他的名字叫做user_agents

pip install pyyaml ua-parser user-agents

>>> ua_string = 'Mozilla/5.0 (iPhone; CPU iPhone OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9B179 Safari/7534.48.3'

>>> # 浏览器属性

>>> user_agent = parse(ua_string)

>>> user_agent.browser

Browser(family=u'Mobile Safari', version=(5, 1), version_string='5.1')

>>> user_agent.browser.family

u'Mobile Safari'

>>> user_agent.browser.version

(5, 1)

>>> user_agent.browser.version_string

'5.1'

>>> # 操作系统属性

>>> user_agent.os

OperatingSystem(family=u'iOS', version=(5, 1), version_string='5.1')

>>> user_agent.os.family

u'iOS'

>>> user_agent.os.version

(5, 1)

>>> user_agent.os.version_string

'5.1'

>>> # 设备属性

>>> user_agent.device

Device(family=u'iPhone', brand=u'Apple', model=u'iPhone')

>>> user_agent.device.family

u'iPhone'

>>> user_agent.device.brand

u'Apple'

>>> user_agent.device.model

u'iPhone'

>>>

>>> str(user_agent)

'iPhone / iOS 5.1 / Mobile Safari 5.1'

批量解析：采用apply函数

• data['user_agent'] = data['ua'].apply(lambda x:parse(x))
