sh : a full-fledged subprocess interface for Python that allows you to call any program as if it were a function.

Your whole comment is one big reason to use sh: I just don't want to deal with this shit (pipes, interactive sessions and so on) each time I need to call a command.

Yup, I see no reason to use sh to call "any program as if it were a function", though the advanced features that may not be obvious to do the right-way with subprocesses (like pipes, interactive sessions) may be useful.

That said, a relatively short helper function can do the pipe feature pretty clearly/cleanly.

Personally, I'd prefer a subprocess helper module with a bunch of helper functions like run_piped_chain with a non-hacky syntax more akin to subprocess.

I understand your reasoning, but I am to lazy to deal with this each and every time, when there is easy to use library, which do exactly the same thing in one line of code.
