You pass in the name of the field that has the credit card type and the field with the credit card number. The credit card type should be one of "visa", "mastercard", "amex", "dinersclub", "discover", "jcb".

You must check the expiration date yourself (there is no relation between CC number/types and expiration dates).

>>> cc = CreditCardValidator()
>>> cc.to_python({'ccType': 'visa', 'ccNumber': '4111111111111111'})
{'ccNumber': '4111111111111111', 'ccType': 'visa'}
>>> cc.to_python({'ccType': 'visa', 'ccNumber': '411111111111111'})
