hi
i want to learn about how may i do an application in python that read, write and even do some functions by calling bash commands in linux

imagine this:

an app that allows you to put a value, then run a command with that value as a "-" variable, so you can do something like

but... by choosing or writing the freq value using a gui or even options in a command-line python script.

something like "processor.py -freq 1"

With read write I supposed you mean reading/writing files? There's a method in python called open.

About being able to pass them as arguments to the python script itself you've got a lot of options. The simplest is to use the sys module and optionally parse the arguments yourself depending on how advanced you want it. Here's an example of a script that prints the first argument that you pass to the script, basically an echo script, but we set it as a positional argument and force it to be passed.

But as I mentioned above you'd need to parse it yourself if you want to have options starting with "-". In this case it'd be simpler to use the argparse module where you can choose what options you want and what values they need to be( int, string ) or if they're just boolean options. A basic google search would've gotten you all the answers - suggestion would be to do a trial and error and just test your way forward until you get the basic understanding of how things work, get familiar with the modules( os, sys ).

If you want to have a gui you'd need to use a library like tkinter, Qt, Gtk+, Kivy etc.
