Hello I am trying to make a function in python to generate valid IMEI numbers so here is my function.The IMEI validation uses the Luhn algorithm so I am trying to implement it in my script.
def getImei():
num = ''
suma = 0
for i in range(0,13):
digit = random.randrange(0,9)
suma = suma + digit
num = num + str(digit)
suma = suma * 9
digit = suma % 10
num = num + str(digit)
return num
The function however fails to generate valid IMEI numbers. I found an article on wikipedia that tells me how to generate the check digit ( http://en.wikipedia.org/wiki/Luhn_algorithm )
The check digit (x) is obtained by computing the sum of digits then computing 9 times that value modulo 10 (in equation form, (67 * 9 mod 10)). In algorithm form: 1.Compute the sum of the digits (67). 2.Multiply by 9 (603). 3.The last digit, 3, is the check digit.
Am I missing something or the wiki is wrong ?
