Python Versions We Support

[Fumbani Banda]

Hi everyone, I would like to update the Wiki page on Python versions that we support. Currently, the page is blank.

I was wondering if there's a way, I can get the list of all the Python versions supported by sympy.

P.S: My name is Fumbani Banda and I have recently developed an interest in contributing to open-source. I'm an undergraduate in Computer Science and I use python to code my projects. 

I have read the documentation and installed sympy. I have followed the getting started tutorials and I have grasped some components of what sympy is about.

Hi Fumbani,

If you look at the PyPI page for sympy, you can see the list of
officially supported Python versions
(https://pypi.org/project/sympy/). Currently that list is 3.8, 3.9 and
3.10.

The list is generated from sympy's setup.py file:
https://github.com/sympy/sympy/blob/master/setup.py#L344-L348

You will see that 3.11 is also listed in the setup.py file, but
presumably a new release has not been built since 3.11 was added.

Regards,
Simon

Hi Simon,

This is very helpful.

Hi Simon,

Yes, I think that SymPy 1.11 was released shortly before CPython 3.11.
It was tested against 3.11 through all the beta versions etc.

I don't immediately have 3.11 to hand. Does pip still install SymPy
from PyPI under 3.11?

I have used sympy (sympy.physics.mechanics) for the last two weeks with python 3.11, and all seems fine. Of course I do not use the finer points of sympy, just what's needed for sympy.physics.mechanics.

Hi Oscar,

The sympy wheel is marked py3-none-any, so it installs on any version
of Python 3.

This is the page for Python versions we support
https://github.com/sympy/sympy/wiki/Python-version-support-policy. The
current policy is to support all Python versions that are not end of
life (see https://devguide.python.org/versions/#versions), although,
I'd like to shorten that list
(https://github.com/sympy/sympy/issues/21884). I'm also planning on
moving this page from the wiki to the documentation (I may do this in
https://github.com/sympy/sympy/pull/23879 or in a future PR).

Great idea to move into the documentation which Python versions SymPy supports. I recently encountered a package that didn't support 3.11, and that wasn't started on the package's Quick Start page, so it caused me confusion.

Which quickstart page are you referring to?

We should avoid mentioning Python versions on too many pages. Python
releases every year, and we will basically always support the latest
version. But we can't keep up with updating a dozen pages with the
latest Python version all the time. IMO the only pages that should
explicitly mention Python versions are the Python version support page
and the release notes pages (which wouldn't be updated once the
release happens).

This was the quickstart page of a different package unrelated to SymPy, specifically Airflow.

Hi everyone,

Thank you for the replies and the great discussion.

I went through all the links and learned of the discussion when sympy wanted to adopt NEP 29 but I guess that hasn't happened because Python support policy says we use EOL.

I simply updated the wiki here with the content from the Python support policy.

Regards,

Fumbani
