Package: incf.countryutils
incf.countryutilsprovides a convenience API on top of
a list of countries by continent (data_file) as found onWikipedia(a copy is included in the distribution).It supports transformations between the different types of country
codes and names like in:>>> from incf.countryutils import transformations
>>> transformations.cca2_to_ccn('de')
'276'
>>> transformations.ccn_to_cn(276)
'Germany'Country codes supported arenumeric(ccn; internal reference format),two letter country codes(cca2), andthree letter country codes(cca3).
In addition,incf.countryutilsknows thesimple English nameof each
country (cn) as well as theofficial English name.Transformation names follow the pattern<f1>_to_<f2>wheref1andf2refer to country codes or names. All transformations to and from the reference
format (ccn) are provided.When providing a numeric country code as an argument integer as well as
string representations are accepted.Moreover, there are some combined transformations available for convenience.
Most notably this is <any country code>_to_<simple or official name>:>>> transformations.cc_to_cn('FR')
'France'
>>> transformations.cc_to_cn('FRa')
'France'
>>> transformations.cc_to_cn('250')
'France'
>>> transformations.cc_to_cn(250)
'France'
>>> transformations.cc_to_con(250)
'French Republic France'Lookup by name is only supported for the simple English name:>>> transformations.cn_to_ccn('Italy')
'380'
>>> transformations.ccn_to_con('380')
'Italian Republic Italy'ContinentsBased on the data fromWikipediaincf.countryutilsallows looking
up the continent a country belongs to (ctn: continent name;ctca2: two letter continent code):>>> transformations.cn_to_ctn('Italy')
'Europe'
>>> transformations.cca_to_ctn('us')
'North America'Continents have two letter codes as well like in:>>> transformations.cca_to_ctca2('usa')
'NA'Given a continent, one can obtain its constituent countries:>>> transformations.ctca2_to_ccn('AN')
['010', '074', '260', '334', '239']Alternative API (OO)There is an alternative, more object-oriented API based on the
notion ofCountryandContinenttypes. On creation, a country
or continent needs to be passed a name or code:>>> from incf.countryutils.datatypes import Country
>>> china = Country('China')
>>> china
<incf.countryutils.datatypes.Country object at 0x...>The country’s names and codes are available as attributes:>>> china.name
'China'
>>> china.official_name
"People's Republic of China"
>>> china.numeric
'156'
>>> china.alpha2
'CN'
>>> china.alpha3
'CHN'and thecontinentproperty refers to a correspondingContinentinstance:>>> china.continent
<incf.countryutils.datatypes.Continent object at 0x...>which in turn has the following attributes:>>> china.continent.name
'Asia'
>>> china.continent.alpha2
'AS'Asking a continent for its constituent countries returns
a generator object returning country instances in turn:>>> china.continent.countries
<generator object at 0x...>
>>> china.continent.countries.next()
<incf.countryutils.datatypes.Country object at 0x...>
>>> [c.name for c in china.continent.countries]
['Afghanistan', 'Armenia', 'Azerbaijan', 'Bahrain', ...]Related packagesThe use case driving the development of this package has been the
wish to be able to get at a continent given a country where the
country can be specified in any ISO 3166 compliant way.There is alsopycountrywhich handles also regional subdivision,
currency, and language. It may also gain the capabilities provided
here but note thatpycountryrequireslxmlwhich may not always
be readily available on some platforms.Finally, for those interested in looking up countries by IP address
