python3通过luhn算法快速验证信用卡卡号，python用起来就是爽，很简单的三行代码就可以验证信用卡卡号是否有效
def luhn_check(num): ''' number - list of reversed digits ''' digits = [int(x) for x in reversed(str(num))] check_sum = sum(digits[::2]) + sum((dig//10 + dig%10) for dig in [2*el for el in digits[1::2]]) return check_sum%10 == 0if __name__ == __main__: print(luhn_check(543298376))
希望本文所述对大家的python3程序设计有所帮助。
