You are making the problem unnecessarily complex. For the example scenario
start with a dict that maps host to ip:
host2ip = {
"PC1": "192.168.0.1",
"PC2": "192.168.0.2",
"PC3": "192.168.0.3",
}
host, ip = raw_input("Enter host and ip: ").split()
if host not in host2ip:
print "adding", host
host2ip[host] = ip
else:
old_ip = host2ip[host]
if old_ip == ip:
print "no changes necessary"
else:
print "updating ip for", host, "from", old_ip, "to", ip
host2ip[host] = ip
Then proceed and come up with an unambiguous description of what to do with
mac and time in plain english, and add or modify data structures as
necessary.
