What are Python sockets used for?

Python sockets let you build direct network connections — TCP for reliable web servers, UDP for fast streams. Core for any backend beyond frameworks.

TCP vs UDP: which for HTTP servers?

TCP always for HTTP — it guarantees order and delivery. UDP's for speed-critical stuff like video calls, not web pages.

How to make a basic HTTP server in Python?

Use socket.socket(AF_INET, SOCK_STREAM), bind/listen/accept, parse request bytes, send HTTP-formatted response. Full code above serves browsers instantly.
