countryguess 0.3.0

countryguess looks up country information by country codes or name matching. It tries to be lean (but not mean) and fast: All dependencies are in the Python Standard Library and country data is loaded lazily on demand.

Code: Codeberg
Package: PyPI

Usage

guess_country() uses the default country data that is already packaged.

>>> from countryguess import guess_country
>>> guess_country("britain")
{
    'name_short': 'United Kingdom',
    'name_official': 'United Kingdom of Great Britain and Northern Ireland',
    'iso2': 'GB',
    'iso3': 'GBR',
    ...
}
>>> guess_country("no such country")
None
>>> guess_country("no such country", default="Oh, well.")
'Oh, well.'
>>> guess_country("PoRtUgAl", attribute="iso2")
'PT'
>>> guess_country("TW", attribute="name_official")  # 2-letter code lookup
'Republic of China'
>>> guess_country("tWn", attribute="name_short")    # 3-letter code lookup
'Taiwan'

Matching by regular expression can be extended by mapping ISO2 codes to re.Pattern objects.

>>> regex_map = {
...     "MN": re.compile(r'^mongol\s+uls$', flags=re.IGNORECASE),
...     "JP": re.compile(r'^ni(?:pp|h)on', flags=re.IGNORECASE),
... }
>>> guess_country("Mongol Uls", attribute="name_short", regex_map=regex_map)
'Mongolia'
>>> guess_country("Nippon", attribute="name_short", regex_map=regex_map)
'Japan'

You can also create a CountryData instance yourself to provide your own country data in a JSON file.

>>> from countryguess import CountryData
>>> countries = CountryData("path/to/countries.json")
>>> countries["vIeTnAm"]
{'name_short': 'Vietnam', ...}
>>> countries["vn"]
{'name_short': 'Vietnam', ...}
>>> countries["asdf"]
KeyError: 'asdf'
>>> countries.get("asdf")
None
>>> countries.get("kuwait")
{'name_short': 'Kuwait', ...}

On CountryData instances, every key in the JSON data is accessible as a method.

>>> countries.name_official("portugal")
'Portuguese Republic'
>>> countries.continent("vanuatu")
'Oceania'

Country Lookup

Countries are identified by name, 2-letter code (ISO 3166-1 alpha-2) or 3-letter code (ISO 3166-1 alpha-3). All identifiers are matched case-insensitively.

Names are matched with regular expressions that are stored in the JSON data. If that fails, fuzzy matching against name_short and name_official is done with difflib.

Country Data

Country information is read from a JSON file. One is shipped with the package, but you can also provide your own to the CountryData class as described above. The information in the default file was gratefully extracted from country-converter. (Many thanks!)

The country data file must contain a list of JSON objects. Each object represents a country that must contain at least the following keys:

• name_short
• name_official
• iso2
• iso3
• regex

Command Line Interface

countryguess comes with a simple CLI with the same name. It takes one or two arguments:

$ countryguess oman
{
    "name_short": "Oman",
    "name_official": "Sultanate of Oman",
    ...
}
$ countryguess 'puerto ricco' name_official
