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

Answer 1

解析它，改变它，打印它！

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