Python A Simple Chat Script

 This is a simple chat application using python socket library. The script accept the following input arguments:

Argv 1 = enter 1(server) or 2(client)

Argv 2 = port number

Argv 3 = host

To run the program as server: python popchat.py 1 8080 test(any string)

To run the program as a client: python popchat.py 2 8080 hostname

 If run on a different pc, replace the host in server with '0.0.0.0' and firewall may have to be disabled(be careful).

I use the following code to disable/enable my firewall:(Windows 10):

1 2	import subprocess subprocess.check_call('netsh.exe advfirewall set publicprofile state on')

Use "on" to enable the firewall and "off" to disable.

The output:

The code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45
