-----------------------
|

|
* :pep:`594` removed 19 modules from the standard library,
|
||||||
|
deprecated in Python 3.11:
|
||||||
|
|

|
||||||
|
|
||||||
|
* :mod:`!cgi` and :mod:`!cgitb`.
|
||||||
|
|
||||||
|
* ``cgi.FieldStorage`` can typically be replaced with
|
||||||
|
:func:`urllib.parse.parse_qsl` for ``GET`` and ``HEAD`` requests,
|
||||||
|
and the :mod:`email.message` module or `multipart
|
||||||
|
<https://pypi.org/project/multipart/>`__ PyPI project for ``POST`` and
|
||||||
|
``PUT``.
|
||||||
|
|
||||||
|
* ``cgi.parse()`` can be replaced by calling :func:`urllib.parse.parse_qs`
|
||||||
|
directly on the desired query string, except for ``multipart/form-data``
|
||||||
|
input, which can be handled as described for ``cgi.parse_multipart()``.
|
||||||
|
|
||||||
|
* ``cgi.parse_header()`` can be replaced with the functionality in the
|
||||||
|
:mod:`email` package, which implements the same MIME RFCs. For example,
|
||||||
|
with :class:`email.message.EmailMessage`::
|
||||||
|
|
||||||
|
from email.message import EmailMessage
|
||||||
|
msg = EmailMessage()
|
||||||
|
msg['content-type'] = 'application/json; charset="utf8"'
|
||||||
|
main, params = msg.get_content_type(), msg['content-type'].params
|
||||||
|
|
||||||
|
* ``cgi.parse_multipart()`` can be replaced with the functionality in the
|
||||||
|
:mod:`email` package (e.g. :class:`email.message.EmailMessage` and
|
||||||
|
:class:`email.message.Message`) which implements the same MIME RFCs, or
|
||||||
|

|
|

|
* :mod:`!crypt` module and its private :mod:`!_crypt` extension.
|
||||||
|
The :mod:`hashlib` module is a potential replacement for certain use cases.
|
||||||
|
Otherwise, the following PyPI projects can be used:
|
||||||
|
|
||||||
|
* `bcrypt <https://pypi.org/project/bcrypt/>`_:
