Just a simple python3 script to calculate a german IBAN from given BLZ and Konto-Nr.
On the command line, call chmod +x ./main.py and then run the script with ./main.py BLZ KONTO,
where BLZ and KONTO are the german Bankleitzahl and Kontonummer.
Just clone the repo with git clone https://github.com/INstinct42/simple_iban_calculator.git or download the files manually.
BE CAREFUL! Although the generated IBAN might look correct, only an IBAN generated by a bank is guaranteed to work. Wikipedia on IBAN
