Built With

• AHash
• idna
• memchr
• once_cell
• Public Suffix List

Performance

Extract From Domain

Tests were run on a file containing 10 million random domains from various top-level domains (Mar. 13rd 2022)

Library	Function	Time
PyDomainExtractor	pydomainextractor.extract	1.50s
publicsuffix2	publicsuffix2.get_sld	9.92s
tldextract	__call__	29.23s
tld	tld.parse_tld	34.48s

Extract From URL

The test was conducted on a file containing 1 million random urls (Mar. 13rd 2022)

Library	Function	Time
PyDomainExtractor	pydomainextractor.extract_from_url	2.24s
publicsuffix2	publicsuffix2.get_sld	10.84s
tldextract	__call__	36.04s
tld	tld.parse_tld	57.87s

Installation

pip3 install PyDomainExtractor

Usage

Extraction

import pydomainextractor


# Loads the current supplied version of PublicSuffixList from the repository. Does not download any data.
domain_extractor = pydomainextractor.DomainExtractor()

domain_extractor.extract('google.com')
>>> {
>>>     'subdomain': '',
>>>     'domain': 'google',
>>>     'suffix': 'com'
>>> }

# Loads a custom SuffixList data. Should follow PublicSuffixList's format.
domain_extractor = pydomainextractor.DomainExtractor(
    'tld\n'
    'custom.tld\n'
)

domain_extractor.extract('google.com')
>>> {
>>>     'subdomain': 'google',
>>>     'domain': 'com',
>>>     'suffix': ''
>>> }

domain_extractor.extract('google.custom.tld')
>>> {
>>>     'subdomain': '',
>>>     'domain': 'google',
>>>     'suffix': 'custom.tld'
>>> }

URL Extraction

import pydomainextractor


# Loads the current supplied version of PublicSuffixList from the repository. Does not download any data.
domain_extractor = pydomainextractor.DomainExtractor()

domain_extractor.extract_from_url('http://google.com/')
>>> {
>>>     'subdomain': '',
>>>     'domain': 'google',
>>>     'suffix': 'com'
>>> }

Validation

import pydomainextractor


# Loads the current supplied version of PublicSuffixList from the repository. Does not download any data.
domain_extractor = pydomainextractor.DomainExtractor()

domain_extractor.is_valid_domain('google.com')
>>> True

domain_extractor.is_valid_domain('domain.اتصالات')
>>> True

domain_extractor.is_valid_domain('xn--mgbaakc7dvf.xn--mgbaakc7dvf')
>>> True

domain_extractor.is_valid_domain('domain-.com')
>>> False

domain_extractor.is_valid_domain('-sub.domain.com')
>>> False

domain_extractor.is_valid_domain('\xF0\x9F\x98\x81nonalphanum.com')
>>> False

TLDs List

import pydomainextractor


# Loads the current supplied version of PublicSuffixList from the repository. Does not download any data.
domain_extractor = pydomainextractor.DomainExtractor()

domain_extractor.get_tld_list()
>>> [
>>>     'bostik',
>>>     'backyards.banzaicloud.io',
>>>     'biz.bb',
>>>     ...
>>> ]
