Python Messaging App

A basic console-based, client-server messaging application enabling real-time user communication & file sharing through a server using TCP sockets.

Setup

Run the server: python server.py [port]

Connect a client: python client.py [username] [hostname] [port]

Notes

• The codebase is PEP8 compliant. You can check compliance by running pycodestyle src/. in the terminal.

• The server can handle Keyboard Interrupts.

• The system enforces unique usernames. If a username is already taken, the user will be prompted to enter a new one.

• The log file does not clear after each run. To change this, modify line 32 in server.py from filemode='a' to filemode='w'.
