Running Linux Commands Within Python

As the title suggests, I want to run Linux commands from Python to code, but I wonder if there is a way! More specifically,

I'm currently working on Python on Linux, and I want to write SPICE commands in code within Python to automatically run a program called SPICE.

I looked it up and it was os.There is a system() and subprocess, so I wonder if it is a code that fits the purpose I want to do.

There were many materials running Python on Linux, but there was no data for writing Linux commands on Python, so please give me a lot of advice...!!
