Python 3: Spoof MAC Address: random.randint(), random.choice(), subprocess.run()

'''Spoof MAC address. (as a cybersecurity enhancement)'''
from random import randint
from random import choice
from subprocess import run

# pseudo-randomly generated MAC address
mac_addr = f"{hex(choice(range(16, 255, 2)))[2:]}:\
{hex(randint(16, 256))[2:]}:\
{hex(randint(16, 256))[2:]}:\
{hex(randint(16, 256))[2:]}:\
{hex(randint(16, 256))[2:]}:\
{hex(randint(16, 256))[2:]}"

print(mac_addr)
run(["sudo", "ip", "link", "set", "enp2s0", "address", mac_addr], check=True)

Based on how the first two binary bits in the first octet are used, basically, an even number must be passed to hex(), and, for the convenience of the script, those values should start at hex(16) in order to return a pair of hex characters, instead of one hex character. For example:

>>> hex(15)[2:]
'f'
>>> hex(16)[2:]
'10'

Instead of padding zeros for 0–15, I simply skipped them.
