| :mod:`http` is a package that collects several modules for working with the |
| HyperText Transfer Protocol: |
| |
| * :mod:`http.client` is a low-level HTTP protocol client; for high-level URL |
| opening use :mod:`urllib.request` |
| * :mod:`http.server` contains basic HTTP server classes based on :mod:`socketserver` |
| * :mod:`http.cookies` has utilities for implementing state management with cookies |
| * :mod:`http.cookiejar` provides persistence of cookies |
| |
| :mod:`http` is also a module that defines a number of HTTP status codes and |
| associated messages through the :class:`http.HTTPStatus` enum: |
| |
| .. class:: HTTPStatus |
| |
| .. versionadded:: 3.5 |
| |
| A subclass of :class:`enum.IntEnum` that defines a set of HTTP status codes, |
| reason phrases and long descriptions written in English. |
| |
| Usage:: |
| |
| >>> from http import HTTPStatus |
| >>> HTTPStatus.OK |
| <HTTPStatus.OK: 200> |
| >>> HTTPStatus.OK == 200 |
| True |
| >>> http.HTTPStatus.OK.value |
| 200 |
| >>> HTTPStatus.OK.phrase |
| 'OK' |
| >>> HTTPStatus.OK.description |
| 'Request fulfilled, document follows' |
| >>> list(HTTPStatus) |
| [<HTTPStatus.CONTINUE: 100>, <HTTPStatus.SWITCHING_PROTOCOLS: 101>, ...] |

| In order to preserve backwards compatibility, enum values are also present |
| in the :mod:`http.client` module in the form of constants. The enum name is |
| equal to the constant name (i.e. ``http.HTTPStatus.OK`` is also available as |
| ``http.client.OK``). |
