:mod:`http` --- HTTP modules
============================
.. module:: http
:synopsis: HTTP status codes and messages
**Source code:** :source:`Lib/http/__init__.py`
.. index::
pair: HTTP; protocol
single: HTTP; http (standard module)
--------------
: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
>>> HTTPStatus.OK.value
200
>>> HTTPStatus.OK.phrase
'OK'
>>> HTTPStatus.OK.description
'Request fulfilled, document follows'
>>> list(HTTPStatus)
[<HTTPStatus.CONTINUE: 100>, <HTTPStatus.SWITCHING_PROTOCOLS:101>, ...]
.. _http-status-codes:

======= =================================== ==================================================================
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``).
.. versionchanged:: 3.7
Added ``421 MISDIRECTED_REQUEST`` status code.
.. versionadded:: 3.8
Added ``451 UNAVAILABLE_FOR_LEGAL_REASONS`` status code.
.. versionadded:: 3.9
Added ``103 EARLY_HINTS``, ``418 IM_A_TEAPOT`` and ``425 TOO_EARLY`` status codes.
