It is a simple python messenger which is written with socket module. There are two main code routines, one is the server, and the other is a client. First, each client should make a connection with the server. Then they can communicate via the available server.
To establish a socket connection, a pair of host and port should be defined.
In server code, the host was defined 0.0.0.0, which means that it is listening from all available interfaces. On the client-side, the port should be the same as the server-side, but the host should be defined based on the location of the server and client codes. For example, if both are located on the same machine, the host will be designated as a localhost.
To run the application, server.py should be run once on the server point, then client.py can run on any machine. Just note that if client.py is running on the machine where the server.py is not located, the host variable should change and refer to the public IP of the server-side.
