uap-python

Official python implementation of the User Agent String Parser project.

Build Status

⚠️ THIS IS NOT THE DOCUMENTATION YOU ARE LOOKING FOR (probably) ⚠️

This is the readme for the future 1.0.

For the current releases, see the 0.x branch.

Installing

Just add ua-parser to your project's dependencies, or run

$ pip install ua-parser

to install in the current environment.

Installing ua-parser-rs or google-re2 is strongly recommended as they yield significantly better performances. This can be done directly via the regex and re2 optional dependencies respectively:

$ pip install 'ua_parser[regex]'
$ pip install 'ua_parser[re2]'

If either dependency is already available (e.g. because the software makes use of re2 for other reasons) ua-parser will use the corresponding resolver automatically.

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)
Device(family='Mac', brand='Apple', model='Mac')
