ISO4217 Currency Parser

Parse currencies (symbols and codes) from and to ISO4217.

Similar to iso4217 package, but

data is aquired by scraping wikipedia (see below) - this is repeatable and you stay on the most current data
currency symbols are currated by hand - this allows some fuzzy currency matching
no download and parsing during install
no external dependancies (enum34)

Install:

pip install iso4217parse

Documentation

Each currency is modeled as a collections.namedtuple:

Currency = namedtuple('Currency', [
    'alpha3',     # unicode:       the ISO4217 alpha3 code
    'code_num',   # int:           the ISO4217 numeric code
    'name',       # unicode:       the currency name
    'symbols',    # List[unicode]: list of possible symbols;
                  #                first is opinionated choice for representation
    'minor',      # int:           number of decimal digits to round
    'countries',  # List[unicode]: list of countries that use this currency.
])

Returns:
    List[Currency]: Currency objects found in `value`; filter by country_code.

Data aquisition

Basic ISO4217 currency information is gathered from wikipedia: https://en.wikipedia.org/wiki/ISO_4217 . The tables are parsed with gen_data.py and stored in iso4217parse/data.json. This gives information for alpha3, code_num, name, minor and countries. The currency symbol information is hand gathered from:

individuel wikipedia pages, i.e. EUR has a Denominations -> Symbol section.
http://www.iotafinance.com/en/ISO-4217-Currency-Codes.html
http://www.xe.com/currency/ , i.e. GBP has a Currency Facts -> Symbol section

and stored in iso4217parse/symbols.json. Each currency can have multiple currency symbols - the first symbol in the list is the (opinionated) choice for the currency.

Contribution Note: Possible ways to contribute here:

hand check symbols for currency code.
automatic generation of the iso4217parse/symbols.json file.
