ISO country, subdivision, language, currency and script definitions and their translations
pycountry provides the ISO databases for the standards:
The package includes a copy from Debian’s
pkg-isocodes and makes the data
accessible through a Python API.
Translation files for the various strings are included as well.
No changes to the data will be accepted into pycountry. This is a pure wrapper
around the ISO standard using the
pkg-isocodes database from Debian as is.
If you need changes to the politicial situation in the world, please talk to
the ISO or Debian people, not me.
This is a small project that I maintain in my personal time. I am not interested in personal financial gain. However, if you would like to support the project then I would love if you would donate to Feminist Frequency instead. Also, let the world know you did so, so that others can follow your path.
Countries are accessible through a database object that is already configured upon import of pycountry and works as an iterable:
>>> import pycountry >>> len(pycountry.countries) 249 >>> list(pycountry.countries) Country(alpha_2='AF', alpha_3='AFG', name='Afghanistan', numeric='004', official_name='Islamic Republic of Afghanistan')
Specific countries can be looked up by their various codes and provide the information included in the standard as attributes:
>>> germany = pycountry.countries.get(alpha_2='DE') >>> germany Country(alpha_2='DE', alpha_3='DEU', name='Germany', numeric='276', official_name='Federal Republic of Germany') >>> germany.alpha_2 'DE' >>> germany.alpha_3 'DEU' >>> germany.numeric '276' >>> germany.name 'Germany' >>> germany.official_name 'Federal Republic of Germany'
historic_countries database contains former countries that have been
removed from the standard and are now included in ISO 3166-3, excluding
>>> ussr = pycountry.historic_countries.get(alpha_3='SUN') >>> ussr Country(alpha_3='SUN', alpha_4='SUHH', withdrawal_date='1992-08-30', name='USSR, Union of Soviet Socialist Republics', numeric='810') >>> ussr.alpha_4 'SUHH' >>> ussr.alpha_3 'SUN' >>> ussr.name 'USSR, Union of Soviet Socialist Republics' >>> ussr.withdrawal_date '1992-08-30'
The country subdivisions are a little more complex than the countries itself because they provide a nested and typed structure.
All subdivisons can be accessed directly:
>>> len(pycountry.subdivisions) 4847 >>> list(pycountry.subdivisions) Subdivision(code='AD-07', country_code='AD', name='Andorra la Vella', parent_code=None, type='Parish')
Subdivisions can be accessed using their unique code and provide at least their code, name and type:
>>> de_st = pycountry.subdivisions.get(code='DE-ST') >>> de_st.code 'DE-ST' >>> de_st.name 'Sachsen-Anhalt' >>> de_st.type 'State' >>> de_st.country Country(alpha_2='DE', alpha_3='DEU', name='Germany', numeric='276', official_name='Federal Republic of Germany')
Some subdivisions specify another subdivision as a parent:
>>> al_br = pycountry.subdivisions.get(code='AL-BU') >>> al_br.code 'AL-BU' >>> al_br.name 'Bulqiz\xeb' >>> al_br.type 'District' >>> al_br.parent_code 'AL-09' >>> al_br.parent Subdivision(code='AL-09', country_code='AL', name='Dib\xebr', parent_code=None, type='County') >>> al_br.parent.name 'Dib\xebr'
The divisions of a single country can be queried using the country_code index:
>>> len(pycountry.subdivisions.get(country_code='DE')) 16>>> len(pycountry.subdivisions.get(country_code='US')) 57
Scripts are available from a database similar to the countries:
>>> len(pycountry.scripts) 169 >>> list(pycountry.scripts) Script(alpha_4='Afak', name='Afaka', numeric='439')>>> latin = pycountry.scripts.get(name='Latin') >>> latin Script(alpha_4='Latn', name='Latin', numeric='215') >>> latin.alpha4 'Latn' >>> latin.name 'Latin' >>> latin.numeric '215'
The currencies database is, again, similar to the ones before:
>>> len(pycountry.currencies) 182 >>> list(pycountry.currencies) Currency(alpha_3='AED', name='UAE Dirham', numeric='784') >>> argentine_peso = pycountry.currencies.get(alpha_3='ARS') >>> argentine_peso Currency(alpha_3='ARS', name='Argentine Peso', numeric='032') >>> argentine_peso.alpha_3 'ARS' >>> argentine_peso.name 'Argentine Peso' >>> argentine_peso.numeric '032'
The languages database is similar too:
>>> len(pycountry.languages) 7874 >>> list(pycountry.languages) Language(alpha_3='aaa', name='Ghotuo', scope='I', type='L')>>> aragonese = pycountry.languages.get(alpha_2='an') >>> aragonese.alpha_2 'an' >>> aragonese.alpha_3 'arg' >>> aragonese.name 'Aragonese'>>> bengali = pycountry.languages.get(alpha_2='bn') >>> bengali.name 'Bengali' >>> bengali.common_name 'Bangla'
Locales are available in the
pycountry.LOCALES_DIR subdirectory of this
package. The translation domains are called
isoXXX according to the standard
they provide translations for. The directory is structured in a way compatible
to Python’s gettext module.
Here is an example translating language names:
>>> import gettext >>> german = gettext.translation('iso3166', pycountry.LOCALES_DIR, ... languages=['de']) >>> german.install() >>> _('Germany') 'Deutschland'
For each database (countries, languages, scripts, etc.), you can also look up entities case insensitively without knowing which key the value may match. For example:
>>> pycountry.countries.lookup('de') <pycountry.db.Country object at 0x...>
The search ends with the first match, which is returned.
This release was heavily supported by @zware who fixed some of the issues I overlooked in the last releases and a few enhancements.
This is a major change. The upstream packages have been revamped from the former XML databases to use JSON. They adapted their schemata a bit and thus made some of the structures in pycountry superfluous (yay!). Memory usage went down when all databases are loaded (32.7 MiB down from 83.6 MiB) and performance has gone up (not measured scientifically, but it’s noticable when loading the DBs in an interactive session).
To mark this major change, I’m also switch from the existing (not useful) SemVer-based version numbers to CalVer-based numbers using YY.MM.DD.micro as the pattern.
To avoid adding more complexity I have removed code that really only was necessary because of the complexity of using the XML databases.
Here’s what you need to know:
I updated to iso-codes 3.70 which is a lot fresher than the last release.
Attribute names have changed. There is no longer a mapping going on between the sources and the object attributes. Take a look at the JSON files (or inspect the objects) to see which fields are supported.
You can also inspect the automatically build indexes (db.indices) to see all keys in a database. Not every object supports every attribute - this depends on the quality of the data from pkg-isocodes.
Attribute names are more coherent now, too. Note that “alpha2”, “alpha4”, etc. are now using an underscore as that’s the pattern in the upstream packages. So it’s “alpha_2” now.
HistoricCountries no longer includes countries that still exist. I removed the computed fields that were meant to make it easy to filter.
