$ emacs - q

Visit a new Python buffer and type:

a = b (0)

C-M-f at the beginning of the buffer moves the point immediately to the end
of line. Expected is point after 'a', as in other modes. As another visible
and annoying effect, C-M-k kills more than expected, thus breaking editing
habits.

Note that C-M-b from the end of line moves point to '(', then to 'b', then
to 'a', just as expected.

Adding the following to your .emacs will disable python.el's default
forward-sexp behavior (which works in a ~lispy way):

(add-hook 'python-mode-hook
          (lambda () (setq forward-sexp-function nil)))

The parentheses behavior is a special case I'll document better as a
follow up of #19954.


Cheers,
Fabián.
