1 or 2 ways I can try to figure out and see what is causing your computer to do this. 1 when was the last time you shut off OR was doing on the computer? If your problem gets fixed make sure you close all running apps so the apps don't update while your computer is shutdown. 2 did you or something unplug the cables? Or maybe a virus caused something. Try to unplug every cable and wait about 5-10 minutes and if your computer is still not working, I would advise contacting an administrator.
Hope this helped.
Answer:
from socket import *
hostname = input('Enter the host to be scanned: ')
ip_add = gethostbyname(hostname)
connections = [ ]
for i in range(133, 136):
