Yeah, thanks all, see it.

BTW maybe have a look nonetheless at

ar-parentized-atpt, ar-bracketed-atpt, ar-braced-atpt

in
thing-at-point-utils.el
of
https://code.launchpad.net/~a-roehler/python-mode/python-mode-components

With `C-c (' for example I get the whole expression reported, copied, 
marked, where-ever in parent cursor is.

These just-one-key tools save a lot of time here....
