The Python implementation of Project Woothee, which is multi-language user-agent strings parsers.

https://github.com/woothee/woothee

$ pip install woothee

import woothee
woothee.parse("Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0)")
# => {'name': 'Internet Explorer', 'category': 'pc', 'os': 'Windows 7', 'version': '8.0', 'vendor': 'Microsoft', 'os_version': 'NT 6.1'}

Parse user-agent string and returns a object with keys name, category, os, version, vendor and os_version.

For unknown user-agent (or partially failed to parse), result objects may have value 'UNKNOWN'.

• category
  • labels of user terminal type, one of 'pc', 'smartphone', 'mobilephone', 'appliance', 'crawler' or 'misc' (or 'UNKNOWN')
• name
  • the name of browser, like 'Internet Explorer', 'Firefox', 'GoogleBot'
• version
  • version string, like '8.0' for IE, '9.0.1' for Firefix, '0.2.149.27' for Chrome, and so on
• os
  • ex: 'Windows 7', 'Mac OSX', 'iPhone', 'iPad', 'Android'
  • This field used to indicate cellar phone carrier for category 'mobilephone'
• vendor
  • optional field, shows browser vendor
• os_version
  • optional field, shows version of operating systems

woothee.is_crawler('Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0)')
# => False

Try to see useragent's category is 'crawler' or not, by casual(fast) method. Minor case of crawlers is not tested in this method. To check crawler strictly, use woothee.parse(str)['category'] == 'crawler'.
