Unfortunately that's Python 3.5. You are ahead of time.

"dir" used to be an internal command; back in the day you would have to 
invoke it with (untested)

check_output(["cmd", "/k", 'dir', '/s', '/b', path])

I believe on Windows path may contain wildcards -- or does subprocess escape 
these somehow?

I probably should have kept quiet to let a combined subprocess/windows 
expert chime in -- but now it's too late...
