Luhn Account Number Validator
Project description
The Luhn Algorithm Validator
Tests 14-16 Digit Account Numbers for
Luhn Algorithm Compliance
This module, written in python3, takes a 14, 15, or 16 digit account
number
(for example a credit/debit card number) and applies the Luhn
Algorithm to
the provided data. If the data passes the test the system returns
‘True’,
else the system returns ‘False’.
An account number must be provided as a simple all-digits string
without any
type of separators, including spaces, or the function will return
‘False’.
False values are also returned if the string contains any alpha
characters,
punctuation marks or non-digit characters of any kind.
Using the Luhn Algorithm Validator
’
$ pip3 install Luhn_Algorithm_Validator from luhn import aLuhn >>> cardNumber = '2222222222222224' >>> trueOrFalse = aLuhn.doLuhn(cardNumber) >>> trueOrFalse True >>> cardNumber = '2222222222222222' >>> trueOrFalse = aLuhn.doLuhn(cardNumber) >>> trueOrFalse False
