See attached patch.
lisp/progmodes/python.el (python-shell-completion-native-turn-on-maybe):
If you just start out with python it is not obvious that "readline" is a
pip package that you can install. And as a new user you will get this
warning because readline is not installed.

If you think you may have found a bug in GNU Emacs, please read the
Bugs section of the Emacs manual for advice on

(1) how to tell when to report a bug, and
(2) how to write a useful bug report and what information it needs to have.

You can read the Bugs section of the manual from inside Emacs.
Start Emacs, and press
  C-h r       (to view the Emacs manual)
  m Bugs RET  (to go to the section on Bugs)
Or you can use the standalone Info program:
  info emacs
  m Bugs RET
(Standalone Info is part of the Texinfo distribution, not part of the
Emacs distribution.)

Printed copies of the Emacs manual can be purchased from the Free
Software Foundation's online store at <https://shop.fsf.org/>.

If necessary, you can read the manual without an info program:

    cat info/emacs* | more "+/^File: emacs.*,  Node: Bugs,"


Please first check the file etc/PROBLEMS (e.g. with C-h C-p in Emacs) to
make sure it isn't a known issue.

Thanks, but which file is your patch for?  And how is that patch
relevant to the issue with python.el which you describe?

I probalby made a mistake with the patch.
The new attached one is correct.
It ads a single line in lisp/progmodes/python.el.

Could you provide a recipe for how to reproduce the error you see?

Thanks in advance.
