Project Description

This module allows you to get the public suffix of a domain name using the Public Suffix List from http://publicsuffix.org

A public suffix is a domain suffix under which you can register domain names. Some examples of public suffixes are .com, .co.uk and pvt.k12.wy.us. Accurately knowing the public suffix of a domain is useful when handling web browser cookies, highlighting the most important part of a domain name in a user interface or sorting URLs by web site.

This Python module includes with a copy of the Public Suffix List so that it is usable out of the box. Newer versions try to provide reasonably fresh copies of this list. It also includes a convenience method to fetch the latest list.

The code is a fork of the publicsuffix package and uses the same module name and base API.

The code is MIT-licensed and the publicsuffix data list is MPL-2.0-licensed.

Usage

Install with:

pip install publicsuffix2

The module provides a function to query a domain name:

>>> from publicsuffix import get_public_suffix
>>> get_public_suffix('www.example.com')
'example.com'
>>> get_public_suffix('www.example.co.uk')
'example.co.uk'
>>> get_public_suffix('www.super.example.co.uk')
'example.co.uk'

This function loads and caches the public suffix list.

For more control and compatibility, there is also a class that parses a Public Suffix List and allows the same queries on individual domain names:

>>> from publicsuffix import PublicSuffixList
>>> psl= PublicSuffixList()
>>> psl.get_public_suffix('www.example.com')
'example.com'
>>> psl.get_public_suffix('www.example.co.uk')
'example.co.uk'
>>> psl.get_public_suffix('www.super.example.co.uk')
'example.co.uk'

Note that the host part of an URL can contain strings that are not plain DNS domain names (IP addresses, Punycode-encoded names, name in combination with a port number or a username, etc.). It is up to the caller to ensure only domain names are passed to the get_public_suffix() method.

The get_public_suffix function and the PublicSuffixList class initializer accept an optional argument pointing to a public suffix file. This can either be a file path, an iterable of public suffix lines, or a file-like object pointing to an opened list. The fetch function fetches the latest list:

>>> from publicsuffix import get_public_suffix, fetch
>>> latest = fetch()
>>> get_public_suffix('www.example.com', latest)
'example.com'

This will use the cached latest loaded above:

>>> get_public_suffix('www.example.co.uk')
'example.co.uk'
