Yes, I was going to ask if you also get this echoing for commands typed
in at the prompt or is it just the support functions?  Possibly setting
`comint-process-echoes' could help, though I don't understand why there
is echoing in the first place.

Here is what I get:

    (python-shell-send-string-no-output "import os\nimport sys") ;=> ""
    (python-shell-send-string-no-output "import os; import sys") ;=> ""
    (python-ffap-module-path "os") ;=> "/usr/lib/python3.6/os.py"

By the way, it was reported[1] that using "homebrew" python avoids these
issues, apparently that build uses GNU readline instead of libedit[2].
