Any way to isolate the subdomain?

[ejohb]

Hi,

• http://**www**.example.com
• http://**test.subdomain**.example.com

Is there a furl attribute for the subdomains in URLs - e.g. the ['www'] and ['test','subdomain'] above?

Unfortunately there's currently no reliable way to isolate the subdomain because it's non-trivial to determine the TLD (e.g. .com, .co.uk, etc). See

• https://publicsuffix.org/list/public_suffix_list.dat

In the future, I'll add full TLD support to furl.

In the interim, splitting and rejoining the host by periods (.) is a straightforward, intuitive way to isolate the subdomain assuming a simple, one token TLD (e.g. .com, .net, etc).

>>> from furl import furl
>>> f = furl('http://test.subdomain.example.com/')
>>> tld = f.host.split('.')[-1]
>>> tld
'com'
>>> subdomain = '.'.join(f.host.split('.')[:-2])
>>> subdomain
'test.subdomain'

Does this suffice for your needs for now?
