* Let's use self-documenting variable names
This is complex code so let's use self-documenting function and variable names to help readers to understand.
We should not shorten names to simplify the code formatting but use understandable name and leave to code formatting to psf/black.
I am not sure if `nbor` was supposed to be `neighbour`. ;-)

* Fix ruff errors
Renamed neural_network/input_data.py to neural_network/input_data.py_tf
because it should be left out of the directory for the following
reasons:
1. Its sole purpose is to be used by neural_network/gan.py_tf, which is
itself left out of the directory because of issues with TensorFlow.
2. It was taken directly from TensorFlow's codebase and is actually
already deprecated. If/when neural_network/gan.py_tf is eventually
re-added back to the directory, its implementation should be changed
to not use neural_network/input_data.py anyway.
* updating DIRECTORY.md
* Change input_data.py_tf file extension
Change input_data.py_tf file extension because algorithms-keeper bot is being picky about it
