How to make such a program?

Question

Python

I need to write a simple python program. But it should run another program. That is, a Python program launches another program. It is in both exe and bat. Here is how it is more convenient to work with python. And in the bat (or exe) program there is data input. How do I get a Python program to run that program and then type in a string in the window?

Answer 1

Screenplay for Nolan's new film.
ps Run bat/exe with argument ?

Answer 2

larger line to stdin, for example, it is written here
