It tries to test more corner cases and detailed functionality that is not really useful as module documentation. >>> from stdnum.de import idnr The number should be 11 digits long, should contain only numbers and cannot start with a zero. >>> idnr.validate('116574261809') Traceback (most recent call last): ... InvalidLength: ... >>> idnr.validate('A6574261809') Traceback (most recent call last): ... InvalidFormat: ... >>> idnr.validate('01234567896') Traceback (most recent call last): ... InvalidFormat: ... The first 10 digits of the IdNr is supposed to contain exactly one digit twice (or three times since 2016) and all other digits in the number can only appear once. This tries to catch some corner cases. Note that only the first 10 digits are considered for this. >>> idnr.validate('1234567890 3') # each digit once Traceback (most recent call last): ... InvalidFormat: ... >>> idnr.validate('1123456789 0') # one digit twice '11234567890' >>> idnr.validate('1112345678 6') # one digit three times '11123456786' >>> idnr.validate('1111234567 8') # one digit four times Traceback (most recent call last): ... InvalidFormat: ... >>> idnr.validate('1122345678 5') # two digits more than once Traceback (most recent call last): ... InvalidFormat: ...
