http — HTTP modules

Source code: Lib/http/__init__.py

http is a package that collects several modules for working with the HyperText Transfer Protocol:

http is also a module that defines a number of HTTP status codes and associated messages through the http.HTTPStatus enum:

class http.HTTPStatus

New in version 3.5.

A subclass of 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>, ...]

Changed in version 3.7: Added 421 MISDIRECTED_REQUEST status code.

New in version 3.8: Added 451 UNAVAILABLE_FOR_LEGAL_REASONS status code.
