While it's technically possible to do exactly that in Python (using
subprocess as you describe), there's usually a more efficient and
cleaner method of achieving the same goal. With a port such as you
describe, it's probably best to go right back to the conceptual level
and work out what exactly you're trying to do, and then look at
implementing that in Python. You'll end up with much cleaner code at
the end of it.
For an initial guess, I would say that you'll use subprocess to invoke
lspci, but then everything else will be done in Python directly.
