Install

$ pip install iso10383

Usage

The package is relatively easy to use. The MIC class is the enum that contains all the entries:

>>> from iso10383 import MIC
>>> MIC.xnys.value
MICEntry(
    mic='XNYS',
    market_name='NEW YORK STOCK EXCHANGE, INC.',
    market_category_code=<MCC.nspd: 6>,
    creation_date=datetime.date(2005, 5, 23),
    status=<Status.active: 0>,
    city=<City.new_york: 208>,
    operating_mic=None,
    institution_description=None,
    legel_entity_name=None,
    legal_entity_identifier=None,
    acronym='NYSE',
    iso_country_code=<ISOCC.us: 137>,
    website='www.nyse.com',
    last_update_date=datetime.date(2005, 5, 23),
    last_validation_date=None,
    expiry_date=None,
    comments=None
)

Each MICEntry has the following attributes, which correspond to those found in the specification:

mic                     : str
market_name             : str
market_category_code    : MCC
creation_date           : datetime.date
status                  : Status
city                    : City          | None
operating_mic           : MICEntry      | None
institution_description : str           | None
legel_entity_name       : str           | None
legal_entity_identifier : str           | None
acronym                 : str           | None
iso_country_code        : ISOCC         | None
website                 : str           | None
last_update_date        : datetime.date | None
last_validation_date    : datetime.date | None
expiry_date             : datetime.date | None
comments                : str           | None

MCC, Status, City, and ISOCC are supporting enums that can be imported separately.

The operating/segment column is notably not present, and is instead indicated by the presence of the operating_mic attribute (that is, whether or not it is None).

Notes

Given the large number of entries in the ISO 10383 specification, hard-coding an enum would cause major performance issues with intellisense and linters. For this reason, a dummy enum was hardcoded, and is then replaced by deserializing the contents at runtime. This means there is a small performance hit (on the order of milliseconds) at runtime when the module is imported.
