printing bytes to stdout in Py3

[Peter Billam]

Greetings. (Newbie warning as usual) In Python3, sys.stdout is a
io.TextIOWrapper object; but I want to output bytes
  (e.g. muscript -midi t > t.mid )
and they're coming out stringified :-(  How can I either change the
encoding on sys.stdout, or close sys.stdout and reopen it in 'b'
mode, or dup(fd) it first, or whatever the right thing to do is ?

Regards,  Peter
