Answer

It sounds like subprocess is what you want. It allows you to make command line calls by passing arguments to .run() method.

For example, you can call the ls bash command to get a list of files in the current directory.

import subprocess as sp
out = sp.run("ls", capture_output=True)
print(out.sdtout)
