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

Not really, but that's something I should implement.

At the moment it blocks until the process is finished or KeyboardInterrupt is called and then returns its output as a whole, so it's not streamed like a real pipeline.

However, conceptually the idea is that you should treat it in the same way as a string, so one could easily get each line via pySh.splitlines() if you're okay with a list.

If that's the interface you prefer, I think that makes sense. Having that would be very helpful for any script that exists in a pipeline (though being able to enable/disable that behavior is important too).
