Feature Type

  • Adding platform support

Problem Description

Currently, Python 3.12 isn't fully supported in the Pandas library.

Feature Description

The solution we'd like to see is full support for Python 3.12, including testing in Continuous Integration (CI) and the publishing of compatible wheels to PyPI.

Alternative Solutions

Not applicable in this case, as the goal is specific to supporting a new version of Python.

Additional Context

Python 3.12 is expected to be released as stable later this year, bringing several new features and deprecations that can impact the Pandas library, including:

  • New grammar features:
    • PEP 701: Syntactic formalization of f-strings
  • New typing features:
    • PEP 688: Making the buffer protocol accessible in Python
    • PEP 692: Using TypedDict for more precise **kwargs typing
    • PEP 695: Type Parameter Syntax
    • PEP 698: Override Decorator for Static Typing
  • Important deprecations, removals, or restrictions:
    • PEP 623: Remove wstr from Unicode
    • PEP 632: Remove the distutils package

These changes may have implications for the usage and operation of the Pandas library, making it necessary for the library to adapt to this new version.

Pandas is one of the most used packages and a package on which many other packages depend, so early support will help speed up Python 3.12 adoption. It would be beneficial to have full Python 3.12 support in Pandas by the time Python 3.12.0 beta 1 gets released. This includes testing in CI and publishing wheels to PyPI.

Hi,
Thanks for the bug report.
We need at least numpy/Cython support before we can start on the pandas side, so gonna mark as blocked pending numpy/numpy#23808 (need at least numpy wheels). This means wheels will be out a little later than usual, but hopefully we can still get some in before the 3.12 final release.

Cython side should be OK as far as I can tell.

Thanks! That should be numpy/numpy#23808, right?

I see Python 3.12 wheels are now on PyPI for Pandas 2.1.1! Awesome work!

Python 3.11, 3.12 and Debian Bullseye compatibility (#178)
35f09f9 
- Debian Bullseye and pyenv was picking up old web3-ethereum-defi version
- Create a Docker script to check installation on Debian Bullseye
- This did not then use the correct version of [safe-pysha3](https://github.com/5afe/pysha3), but picked up the old pysha3 package
- Make `pyproject.toml` to say we are compatible all they way to Python 3.12
- [pkgutil compatibility fixes](https://stackoverflow.com/questions/77364550/attributeerror-module-pkgutil-has-no-attribute-impimporter-did-you-mean).
- [Upgrade to Pandas 2.x](pandas-dev/pandas#53665), needed for Python 3.12 compatibility
- Upgrade to the latest Web3.py 6.x version
- Python 3.12 changes `ast` module and this has breaking changes with `eth_trace` library. Workaround them.
- Disable `test_fallback_double_fault` because new Web3.py does not like `MagicMock` results
- Bump to `zope.dottedname` 6.0 needed [for Python 3.11 compatibility](https://pypi.org/project/zope.dottedname/)
