Quick Start
Retrieve all data on a user-agent string
>>> from ua_parser import parse
>>> ua_string = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.104 Safari/537.36'
>>> parse(ua_string) # doctest: +NORMALIZE_WHITESPACE, +ELLIPSIS
Result(user_agent=UserAgent(family='Chrome',
major='41',
minor='0',
patch='2272',
patch_minor='104'),
os=OS(family='Mac OS X',
major='10',
minor='9',
patch='4',
patch_minor=None),
device=Device(family='Mac',
brand='Apple',
model='Mac'),
string='Mozilla/5.0 (Macintosh; Intel Mac OS...Any datum not found in the user agent string is set to None:
>>> parse("")
Result(user_agent=None, os=None, device=None, string='')
Extract only browser data from user-agent string
>>> from ua_parser import parse_user_agent
>>> ua_string = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.104 Safari/537.36'
>>> parse_user_agent(ua_string)
UserAgent(family='Chrome', major='41', minor='0', patch='2272', patch_minor='104')For specific domains, a match failure just returns None:
>>> parse_user_agent("")
Extract OS information from user-agent string
>>> from ua_parser import parse_os
>>> ua_string = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.104 Safari/537.36'
>>> parse_os(ua_string)
OS(family='Mac OS X', major='10', minor='9', patch='4', patch_minor=None)Extract device information from user-agent string
>>> from ua_parser import parse_device
>>> ua_string = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.104 Safari/537.36'
>>> parse_device(ua_string)
