Python Tutorial: HTTP in Python
Make HTTP requests and build simple servers. requests, urllib, and http.server.

APIs power the modern world. Send a GET request to fetch data. POST to submit it. Parse the JSON response. Build your own server.
Python makes all of this surprisingly simple. Ten steps.
What you'll learn in this Python http in python tutorial
This interactive Python tutorial has 8 hands-on exercises. Estimated time: 20 minutes.
- The internet is just HTTP — Every time your browser loads a page, every time your app fetches data from an API — it's using HTTP (HyperText Transfer…
- requests — urllib but human — urllib works but is verbose. The `requests` library makes HTTP in Python actually enjoyable:
- Query parameters — APIs let you filter results with query parameters — the `?key=value` part of a URL.
- POST — sending data — GET retrieves data. POST sends data — creating a new resource:
- Headers — send metadata — HTTP headers carry metadata — authentication tokens, content type, user agent, language preferences.
- raise_for_status() — check for errors — `requests.get()` does NOT raise an exception for HTTP error codes (404, 500, etc.) — it succeeds and returns the error r…
- Sessions — reuse connections — Every `requests.get()` opens a new TCP connection. For many requests to the same server, that's slow.
- Build an API client — Final challenge — no starter code.
