Is there a way to do multiple calls in the same ‘session’ in Popen? For instance, can I make a call through it and then another one after it without having to concatenate the commands into one long string?

You’re not ‘making a call’ when you use popen, you’re running an executable and talking to it over stdin, stdout, and stderr. If the executable has some way of doing a ‘session’ of work (for instance, by reading lines from stdin) then, yes, you can do it. Otherwise, you’ll need to exec multiple times.
subprocess.Popen is (mostly) just a wrapper around execvp(3)
