That message might be wrongly sent from python-mode.el
M-x locate RET my-file RET
might tell the location.

Here melpa installs into ~/emacs.d, maybe have a look there.

HTH,
Andreas

This is the content of my folder ~/emacs.d/elpa/python-mode-20161124.930/:
    - python-mode.el
    - python-mode-autoloads.el
    - python-mode-pkg.el
    - completion/
        - pycomplete.el
        - pycomplete.py

what am I missing?

This indicates a rather recent python-mode.el Still encountering the bug?

Yes, I still have this (apparently) random behavior of the cursor jumping (and this message string appearing).
Can the bug ticket you open solve this issue along the wrong message?

Please open a bug report giving some example, which triggers the bug.

This would mean, you installed the components-branch before loading
python-mode.el, resp. the components-branch is in use.

Opened #1645108 for this messaging.

  Please check you init-file to avoid loading the devel-branch, load
python-mode.el

I haven't installed the devel-branch at all (always used list-packages), plus my init file seems not to contain anything about python-components. Which string shall I look for?

I will try to open a bug report later, however it would be just something like:
-- Try to open a .py file with python-mode and write on a line the string """this is """ and the cursor gets in first position. --

I suspect there must be some interaction with auto completion?

Please start from emacs -Q, loading only python-mode.el and try again.

I started emacs with -Q and loaded a python file with C-x-f (it started in the normal python major mode "Python") then with M-x typed python-mode. As a message I see again 'python-mode loaded from: python-components-mode.el', however the major mode does not seem to change. I say this because it is still written "Python", whereas it should be written "Py" (plus, no functions like 'py-up' are available from M-x).

What am I doing wrong? Thanks for the help thus far

Please don't load a python file, evaluate the python-mode.el first.
Otherwise --as you noticed-- the built-in python.el provides the mode.

Maybe put a (load "my/Path-to-python-mode.el/python-mode.el") in your
init-file - before other python-stuff gets loaded.

I see, thank you. By doing so the problem seems not to happen (no message, no cursor moving) so I suppose that the issue comes from some weird interaction between python-mode and other python specific issues.
The only way to get it now seems to be a thorough test by removing/adding each single line : )
Thanks again for your help Andreas, if I found this interaction, I will post it here later

Ok, I found the culprit: it seems that the package auto-indent-mode is responsible for the interaction.
I ended the unwanted behavior by commenting:

;; (require 'auto-indent-mode)
;; (auto-indent-global-mode)

Thanks again Andreas
