I started first the python process C-c C-p. Then, I run C-c C-c and
the following message was shown:
Warning (python): Your ‘python-shell-interpreter’ doesn’t seem tosupport readline, yet ‘python-shell-completion-native’ was t and"python" is not part of the‘python-shell-completion-native-disabled-interpreters’ list.  Nativecompletions have been disabled locally.

That's a very searchable warning message.
Try upgrading to Emacs 25.2 (preferably 25.3).

For Windows it won't help though. You should just do

    (setq python-shell-completion-native-disabled-interpreters "")

to suppress the warning. In Emacs 26, this will be the default for Windows.
