Project Description

publicsuffixlist

Public Suffix List parser implementation for Python 2.5+/3.x.

  • Compliant with TEST DATA
  • Support IDN (unicode or punycoded).
  • Support Python2.5+ and Python 3.x
  • Shipped with built-in PSL and update scripts.
  • Written in Pure Python. No library dependencies.

Install

publicsuffixlist can be installed via pip or pip3.

$ sudo pip install publicsuffixlist

If you are on a bit old destribution (RHEL/CentOS6.x), you may need to update pip itself before install.

$ sudo pip install -U pip

Usage

from publicsuffixlist import PublicSuffixList

psl = PublicSuffixList()
# uses built-in PSL file

psl.publicsuffix("www.example.com")   # "com"
# longest public suffix part

psl.privatesuffix("www.example.com")  # "example.com"
# shortest domain assigned for a registrant

psl.privatesuffix("com") # None
# None if no private (non-public) part found


psl.publicsuffix("www.example.unknownnewtld") # "unkownnewtld"
# new TLDs are valid public suffix by default

psl.publicsuffix(u"www.example.香港")   # u"香港"
# accept unicode

psl.publicsuffix("www.example.xn--j6w193g") # "xn--j6w193g"
# accept punycoded IDNs by default

Latest PSL can be passed as a file like line-iterable object.

with open("latest_psl.dat", "rb") as f:
    psl = PublicSuffixList(f)

Works with both Python 2.x and 3.x.

Drop-in compat code to replace publicsuffix

# from publicsuffix import PublicSuffixList
from publicsuffixlist.compat import PublicSuffixList

psl = PublicSuffixList()
psl.suffix("www.example.com")   # return "example.com"
psl.suffix("com")               # return ""

Limitation

publicsuffixlist do NOT provide domain name validation. In DNS protocol, most of 8-bit charactors are valid label of domain name. ICANN compliant registries do not accept domain names that have _ (underscore) but hostname may have. (DMARC records, for example.)

Users need to confirm input is valid based on the users’ context.

Partially encoded (Unicode-mixed) Punycode is not supported because of very slow Punycode en/decoding and unpredictable result encoding. If you are not sure the input is valid Punycode or not, use .encode("idna") which is idempotence first.
