This article illustrates the Python3 method of verifying credit card number quickly through Luhn algorithm. Share to everyone for your reference. The specific analysis is as follows:
Python3 through the Luhn algorithm to quickly verify the credit card number, Python is cool, very simple three lines of code can verify that the credit card number is valid
|1 2 3 4 5 6 7||def luhn_check (num): ' Number-list of reversed digits ' digits = [int (x) for x in reversed (str (num))] Check_sum = su M (Digits[::2]) + SUM ((DIG//10 + dig%10) for dig in [2*el to El in Digits[1::2]]) return check_sum%10 = 0 if __name__ = = "__main__": Print (Luhn_check (543298376))|
I hope this article will help you with the Python3 program design.
