tldextract 0.1

Accurately separate the gTLD/ccTLD component from the registered domain and subdomains of a URL.

The tldextract module accurately separates the gTLD and ccTLDs from the registered domain and subdomains of a URL. For example, you may want the ‘www.google’ part of http://www.google.com. This is simple to do by splitting on the ‘.’ and using all but the last split element, however that will not work for URLs with arbitrary numbers of subdomains and country codes, unless you know what all country codes look like. Think http://forums.bbc.co.uk for example.

tldextract can give you the subdomains, domain, and gTLD/ccTLD component of a URL, because it looks up–and caches locally–the currently living TLDs according to iana.org.
