Greatest Common Divisor function with multiple arguments in python

import math
import fractions
def gcdm(*args):
    UaS = sorted(list(set(list(args))))
    if len(UaS) == 1:
        return list(UaS)[0]
    if len(UaS) == 2:
        return fractions.gcd(UaS[0],UaS[1])
    if len(UaS) >= 3:
        pair = fractions.gcd(UaS[0],UaS[1])
        print(pair)
        for i in range(2,len(UaS)):
            pair = fractions.gcd(pair,UaS[i])
        return pair
    return 0

print(gcdm(10,20,30,40,50)) == 10

You can do it with fractions or math module which both have gcd function.

[Short Resume] Old ISBN to new ISBN

ISBN is an acronym for International Standard Book Number.

Old ISBNs are 10 digits long and they were used before year 2007.

Old ISBN can have X on the end (still 10 digits long).
Example: 999-9999-99-X

We don't count minus (sometimes space) signs.
Not every ISBN has the same formatting with minus or space signs.
Can vary.

Example:
999-99999-9-9
999 9999 99 9
999-999-999-9

ISBNs are bought in blocks.

Last digit of 13 or 10 digit ISBN is what's called check digit.

New ISBNs are 13-digits long and we're using it since 2007.

You can convert 10 digit ISBN to 13 digit ISBN and vice-versa (13 digit ISBN to 10 digit ISBN).

For digitally storing ISBNs in database I usually use string data type.
