• fixes Problems while inserting into a table with a Tuple column #417

Notes:

• This PR

  • Some of the changed files initially had minor changes, but after passing them through black/flake8/ruff packages, "cosmetic" changes grew dramatically - sorry for overburdening the PR. However, it may be seen as a shy step to a unified approach on code formatting (to be refined in the following PRs) and adopt black/mypy/ruff and other tools to assure a uniform and ubiquitous approach on the code quality.
  • Drifting towards the f-string formatting seems important, but in this PR it is done partially.

• To do:

  • It would be nice to drop the setup.py support in favour of the pyproject.toml file (a historical document is PEP-621) and modern packaging and dependency managers like hatch, poetry, pdm and so forth. I am willing to do this work in one of the next PRs.
  • According to the status of Python versions, ensuring "python>=3.9" will do (easily achieved with pyproject.toml and a Python PD manager, clarifying the previous point)

The list of selected packages from the virtual environment:

• black : 24.2.0
• clickhouse-cityhash : 1.0.2.4
• clickhouse-driver : 0.2.7
• Cython : 3.0.9
• flake8 : 7.0.0
• freezegun : 1.4.0
• lz4 : 4.3.3
• mypy : 1.9.0
• numpy : 1.26.4
• pandas : 2.2.1
• parametrized : 66.0.2 (there is the latest 66.0.3 -> to be removed in favour of pytest.mark.parametrize)
• pytest : 7.4.4
• ruff : 0.3.2
• zstd : 1.5.5.1

Checklist:

• Add tests that demonstrate the correct behaviour of the change.
• Add or update relevant docs, in the docs folder and in code.
• Ensure PR doesn't contain untouched code reformatting: spaces, etc. -> the changed modules have been passed multiple times through the black and ruff packages;
• Run flake8 and fix issues -> issues fixed, after moving to the pyproject.toml support the linters and any other code-quality packages (a good idea is to adopt the black+mypy+ruff as a dev-qa core) will be tuned in a more explicit way;
• Run pytest no tests failed. See the dev docs -> a test case within the pandas related test suite has been added.
