A complete implementation of Client-Server Communication using Python's built-in
socketlibrary β covering both TCP and UDP protocols with real-time bidirectional messaging.
tcp-server-client
This project demonstrates real-time Client-Server Communication using Python sockets. It implements both TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) with features like timestamps, uppercase conversion, message counting, and graceful exit handling.

python --version # Make sure Python 3.x is installedOpen two terminals simultaneously:
# Terminal 1 β Run Server FIRST python tcp_server.py # Terminal 2 β Run Client SECOND python tcp_client.py
# Terminal 1 β Run Server FIRST python udp_server.py # Terminal 2 β Run Client SECOND python udp_client.py
β οΈ Always start the Server before the Client!
