A tool for cleaning, parsing and ultimately validating Swedish bank account numbers, primarily written to be used for web applications with form data.

Installation

Documentation

Will be available on ReadTheDocs eventually.

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.
