# Filters that could be applied:
#   * currency_name
#   * alphabetical_code
#   * entity
#   * decimal_places
#   * numeric_code
#   * withdrawal_date
# The filters correspond to attributes of `Currency` class

# accept arbitrary filters as key/value pairs
currency = find_currency(currency_name="usd")

Work with pydantic

import inspect

from iso4217 import Currency as _Currency, find_currency
from pydantic import BaseModel, root_validator, StrictInt


class Currency(BaseModel, _Currency):
    __root__: StrictInt

    @root_validator(skip_on_failure=True)
    def humanize(cls, values):
        currency_numeric_code: int = values.get("__root__")
        # inspect.getfullargspec(_Currency.__init__) will contain `self`, so we cut it off
        orig_currency_cls_dunder_init_arg_names = inspect.getfullargspec(_Currency.__init__).args[1:]
        currency = find_currency(numeric_code=currency_numeric_code)
        return {
            k: getattr(currency, k, None)
            for k in orig_currency_cls_dunder_init_arg_names
        }
