Usage

Direct usage for validating a bank account number:

>>> import bankkonto

>>> bankkonto.validate('9029', '5735211')
True

>>> bankkonto.validate('9029', '5735214')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/hbldh/Repos/bankkonto/account.py", line 117, in validate
    bank_account_number, bank_name, bank_account_number[-1]))
bankkonto.exceptions.BankkontoValidationError: Bank account number 5735214 for Länsförsäkringar Bank has invalid control digit: 4`

Clean an entered string containing both clearing number and bank account number:

>>> import bankkonto
>>> cn, bn = bankkonto.clean_and_split('8156-6 111.222.333-2')
>>> print(cn)
'81566'
>>> print(bn)
'1112223332'
>>> bankkonto.validate(cn, bn)
True

There is also a WTForms validator at bankkonto.flask.BankkontoValidator that can be used with e.g. Flask-WTF.
