''' Usage

└─$ python3 MAC-Changer.py -i eth0 -m 00:55:63:44:55:66
[+] Current MAC Addr = 00:a6:63:44:55:5d
>> Changing MAC Address For eth0 To 00:55:63:44:55:66

[+][+] MAC address was succesfully changed to 00:55:63:44:55:66

└─$ python3 MAC-Changer.py -i eth0 -m randomwords
[+] Current MAC Addr = 00:55:63:44:55:66
>> Changing MAC Address For eth0 To randomwords

randomwords: invalid ether address.
[!][!] MAC address didn't changed.

└─$ python3 MAC-Changer.py -i eth0
Usage: MAC-Changer.py [options]

MAC-Changer.py: error: [-][-] Please enter a new MAC address, use -h for more information

Note this script will only used in python3 !!, if you want to use this script with python2 .
In line 41,50 and 55 just remove str() .
