* 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

Conversion of pressure units.
|
|
Available Units:- Pascal,Bar,Kilopascal,Megapascal,psi(pound per square inch),
|
|
inHg(in mercury column),torr,atm
|
|
USAGE :
|
|
-> Import this file into their respective project.
|
|
-> Use the function pressure_conversion() for conversion of pressure units.
|
|
-> Parameters :
|
|
-> value : The number of from units you want to convert
|
|
-> from_type : From which type you want to convert
|
|
-> to_type : To which type you want to convert
