Extract the top-level domain (TLD) from the URL given.
Project description
Extract the top level domain (TLD) from the URL given. List of TLD names is taken from Public Suffix.
Optionally raises exceptions on non-existing TLDs or silently fails (if fail_silently argument is set to True).
Prerequisites
Python 3.6, 3.7, 3.8 and 3.9.
Support for Python 2.7 and 3.5 is available as well.
Documentation
Documentation is available on Read the Docs.
Installation
Latest stable version on PyPI:
pip install tldOr latest stable version from GitHub:
pip install https://github.com/barseghyanartur/tld/archive/stable.tar.gzUsage examples
In addition to examples below, see the jupyter notebook workbook file.
Get the TLD name as string from the URL given
from tld import get_tld
get_tld("http://www.google.co.uk")
# 'co.uk'
get_tld("http://www.google.idontexist", fail_silently=True)
# NoneGet the TLD as an object
from tld import get_tld
res = get_tld("http://some.subdomain.google.co.uk", as_object=True)
res
# 'co.uk'
res.subdomain
# 'some.subdomain'
res.domain
# 'google'
res.tld
# 'co.uk'
res.fld
# 'google.co.uk'
res.parsed_url
# SplitResult(
# scheme='http',
# netloc='some.subdomain.google.co.uk',
# path='',
# query='',
# fragment=''
# )Get TLD name, ignoring the missing protocol
from tld import get_tld, get_fld
get_tld("www.google.co.uk", fix_protocol=True)
# 'co.uk'
get_fld("www.google.co.uk", fix_protocol=True)
# 'google.co.uk'Return TLD parts as tuple
from tld import parse_tld
parse_tld('http://www.google.com')
# 'com', 'google', 'www'Get the first level domain name as string from the URL given
from tld import get_fld
get_fld("http://www.google.co.uk")
# 'google.co.uk'
get_fld("http://www.google.idontexist", fail_silently=True)
# NoneCheck if some tld is a valid tld
from tld import is_tld
is_tld('co.uk)
# True
is_tld('uk')
# True
is_tld('tld.doesnotexist')
# False
is_tld('www.google.com')
# FalseUpdate the list of TLD names
To update/sync the tld names with the most recent versions run the following from your terminal:
update-tld-namesOr simply do:
from tld.utils import update_tld_names
update_tld_names()Note, that this will update all registered TLD source parsers (not only the list of TLD names taken from Mozilla). In order to run the update for a single parser, append uid of that parser as argument.
update-tld-names mozillaCustom TLD parsers
By default list of TLD names is taken from Mozilla. Parsing implemented in the tld.utils.MozillaTLDSourceParser class. If you want to use another parser, subclass the tld.base.BaseTLDSourceParser, provide uid, source_url, local_path and implement the get_tld_names method. Take the tld.utils.MozillaTLDSourceParser as a good example of such implementation. You could then use get_tld (as well as other tld module functions) as shown below:
from tld import get_tld
from some.module import CustomTLDSourceParser
get_tld(
"http://www.google.co.uk",
parser_class=CustomTLDSourceParser
)Custom list of TLD names
You could maintain your own custom version of the TLD names list (even multiple ones) and use them simultaneously with built in TLD names list.
You would then store them locally and provide a path to it as shown below:
from tld import get_tld
from tld.utils import BaseMozillaTLDSourceParser
class CustomBaseMozillaTLDSourceParser(BaseMozillaTLDSourceParser):
uid: str = 'custom_mozilla'
local_path: str = 'tests/res/effective_tld_names_custom.dat.txt'
get_tld(
"http://www.foreverchild",
parser_class=CustomBaseMozillaTLDSourceParser
)
# 'foreverchild'Same goes for first level domain names:
from tld import get_fld
get_fld(
"http://www.foreverchild",
parser_class=CustomBaseMozillaTLDSourceParser
)
# 'www.foreverchild'Note, that in both examples shown above, there the original TLD names file has been modified in the following way:
...
// ===BEGIN ICANN DOMAINS===
// This one actually does not exist, added for testing purposes
foreverchild
...Free up resources
To free up memory occupied by loading of custom TLD names, use reset_tld_names function with tld_names_local_path parameter.
from tld import get_tld, reset_tld_names
# Get TLD from a custom TLD names parser
get_tld(
"http://www.foreverchild",
parser_class=CustomBaseMozillaTLDSourceParser
)
# Free resources occupied by the custom TLD names list
reset_tld_names("tests/res/effective_tld_names_custom.dat.txt")Support for Python 2.7 and 3.5
As you might have noticed, typing (Python 3.6+) is extensively used in the code. However, Python 3.5 will likely be supported until it’s EOL. All modern recent versions (starting from tld 0.11.7) are fully compatible with Python 2.7 and 3.5 (just works with pip install tld).
Install from pip
pip install tldDevelopment tips follow:
Python 2.7
Install locally in development mode
python setup.py develop --python-tag py27Prepare dist
./scripts/prepare_build_py27.shRun tests
tox -e py27Python 3.5
Install locally in development mode
python setup.py develop --python-tag py35Prepare dist
./scripts/prepare_build_py35.shRun tests
tox -e py35Troubleshooting
If somehow domain names listed here are not recognised, make sure you have the most recent version of TLD names in your virtual environment:
update-tld-namesTo update TLD names list for a single parser, specify it as an argument:
update-tld-names mozillaTesting
Simply type:
./runtests.pyOr use tox:
toxOr use tox to check specific env:
tox -e py38Writing documentation
