* `#error BYE_BYE_GOLDEN_SNAKE` * Removing everything related to 2.7 from ci.yml * Commenting-out Centos7 * Removing `PYTHON: 27` from .appveyor.yml * "PY2" removal, mainly from tests. C++ code is not touched. * Systematic removal of `u` prefix from `u"..."` and `u'...'` literals. Collateral cleanup of a couple minor other things. * Cleaning up around case-insensitive hits for `[^a-z]py.*2` in tests/. * Removing obsolete Python 2 mention in compiling.rst * Proper `#error` for Python 2. * Using PY_VERSION_HEX to guard `#error "PYTHON 2 IS NO LONGER SUPPORTED.` * chore: bump pre-commit * style: run pre-commit for pyupgrade 3+ * tests: use sys.version_info, not PY * chore: more Python 2 removal * Uncommenting Centos7 block (PR #3691 showed that it is working again). * Update pre-commit hooks * Fix pre-commit hook * refactor: remove Python 2 from CMake * refactor: remove Python 2 from setup code * refactor: simplify, better static typing * feat: fail with nice messages * refactor: drop Python 2 C++ code * docs: cleanup for Python 3 * revert: intree revert: intree * docs: minor touchup to py2 statement Co-authored-by: Henry Schreiner <henryschreineriii@gmail.com> Co-authored-by: Aaron Gokaslan <skylion.aaron@gmail.com>
