control a linux program with python

[Fifoux082]

Hi,
I am not a software devloper.
I started using Python to help me automate some tasks

I have a custom program who run in Linux, in a command window
after launching the program it gives me a menu and I choose the what I want it to do by pressing 1,2,3...etc
some menu gives me access to other menus,
I don't need the result of what the program does (for now)

this program has no argument so just need to "write" on his command window numbers

Thank you

Not that familiar, but would pipes work to keep it simple?

[Fifoux082]

do you know some examples how to use it

[jefsummers]

Here's a tutorial

thank you, but I need to control it by python

[jefsummers]

Haven't used it by would try Pexpect https://pypi.org/project/pexpect/

The program you start has no command line arguments to control it?
Does the program only output text or does the program provides a gui in terminal via ncurses (looks like Midnight Commander)?

If the program works in text mode, it should be doable with pexpect.
If the program looks like midnight commander, good luck.

the program has no arguments
the program output text, it gives me a list AND every action from me, requires me to enter a number from this list.
I will try pexpect
thank yoou

Then pexpect is what you need.
They provide also some examples.

thank you very much

I didn't code almost since the university, I started using Python 2 months ago with simple scripts but very helpful.
It's sometimes hard for me to find the right "way" of doing things.
thank you for both
