Usage

Albania

from nidx import albania

info = albania.decode("J00101999W")
print(info.birthday)    # 1990-01-01
print(info.sex)         # M
print(info.is_national) # True
print(info.year)        # 1990
print(info.month)       # 1
print(info.day)         # 1

assert albania.is_valid("J00101999W")
assert not albania.is_valid("invalid")

decode raises NidFormatError, NidChecksumError, or NidInvalidDateError on invalid input (all subclasses of NidError, which is a ValueError).

Kosovo

from nidx import kosovo

kosovo.validate("1234567892")  # raises on invalid input

assert kosovo.is_valid("1234567892")
assert not kosovo.is_valid("invalid")
