I have pyreadline installed. It does help in a sense that completion works
then in the inferior python mode, although I get following *Warning* buffer

Warning (python): Python shell prompts cannot be detected.
If your emacs session hangs when starting python shells
recover with ‘keyboard-quit’ and then try fixing the
interactive flag for your interpreter by adjusting the
‘python-shell-interpreter-interactive-arg’ or add regexps
matching shell prompts in the directory-local friendly vars:
  + ‘python-shell-prompt-regexp’
  + ‘python-shell-prompt-block-regexp’
  + ‘python-shell-prompt-output-regexp’
Or alternatively in:
  + ‘python-shell-prompt-input-regexps’
  + ‘python-shell-prompt-output-regexps’
Warning (python): Your ‘python-shell-interpreter’ doesn’t seem to support
readline, yet ‘python-shell-completion-native-enable’ was t and "python" is
not part of the ‘python-shell-completion-native-disabled-interpreters’
list.  Native completions have been disabled locally.



But the *Python* buffer says everythng has been loaded ok


Python 2.7.13 (v2.7.13:a06454b1afa1, Dec 17 2016, 20:53:40) [MSC v.1500 64
bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> python.el: native completion setup loaded
>>>
