@tvalentyn Are __ne__ in window.py L232 and pipeline_test.py L804 also needed to be remove?

[tvalentyn]

I left other ne as is since they had a different implementation, the one in pipeline_test can proabably go as well.

[lazylynx]

Understood, LGTM!

[tvalentyn]

I think we need to verify that Beam's cythonization is using Py3 semantic before merging this or similar changes, otherwise the behavior in cythonized codepath could change.

For example there are directives in some files:

beam/sdks/python/apache_beam/coders/coder_impl.py

Line 18 in 5356056

# cython: language_level=3

but we may not have them in other files. I don't know if there is a way to make it a default when we invoke Cython or build wheels for all files without upgrading to Cython 3 when this becomes default. CC: @robertwb who may have advice.

I'll have to park this change for a bit.

[robertwb]

Let's just put # cython: language_level=3 in all our compiled files for now. There's few of them, we could just touch the non-compiled files with this PR if we want.

[tvalentyn]

sg, put together #14198; running some suites & internal performance tests on it just in case.
