Increase / Decrease Mac Address in Python from String

hex, python, python-2.7, regex

Solution

Parse it, change it, print it!

def change_mac(mac, offset)
    return "{:012X}".format(int(mac, 16) + offset)

Problem

I have a mac address in string form. I am interested in taking the Mac string and increasing / decreasing it by 1 value while keeping the integrity of Hex in Python Ex: 000000001F -1: 000000001E +1: 0000000020
