Thanks for the PR @nvanommeren and @sophievdberg! The CI caught some errors which I think you can solve locally if you run pre-commit. Let us know if you need help.

Thanks @noatamir, fixed some small problems. There are still quite some tests failing in pandas/tests/computation/test_eval.py::TestEval::test_simple_cmp_ops - just to check: should we update these tests as well?

Yeah Series.isin(df) should raise IMO

Thx! @nvanommeren Could you update the tests?
