In Python Mode (from "python.el"):
 - M-a runs the command python-nav-backward-block
 - M-e runs the command python-nav-forward-block
 - M-k runs the command kill-sentence

For consistency, M-k could kill to the end of block, instead.  Here is 
an idea:

--

(defun point-after/rr ($movement-command &rest $args)
  "Return what the value of point would be after executing 
$MOVEMENT-COMMAND
with $ARGS."
  (save-excursion
    (apply $movement-command $args)
    (point)))


(defun python-kill-block/rr (&optional $arg)
  "Kill from point to end of Python block.  It doesn't fix indentation.

With $ARG, repeat.  With negative argument, kill $ARG times
backward to previous Python block."
  (interactive "p")
  (or $arg (setq $arg 1))
  (kill-region (point)
               (point-after/rr #'python-nav-forward-block $arg)))


(define-key python-mode-map (kbd "M-k") #'python-kill-block/rr)

Context-sensitive versions of M-a and M-e could deal with sentences when 
in comments or strings, and do something else in code (like Python Mode 
does).
