2-WAY TCP TELNET CHAT

chat.py

#This program is messy. For some reason I can't get it to accept another connection after the current one is terminated.
#Program requires restart after connection sadly. 
#I copied and pasted a lot of code to create it (from the internet and my past scripts), so don't expect it to be too good.
#If anyone knows how to fix its issues that would be exteremely helpful.
