[Orgmode] [babel] Possible bug: (mis)handling tuples for :return value in Python [7.4 (release_7.4.153.ga0b8)]

[Scott May]

I do not think that =org-babel-read= is correctly handling Python
tuples that are returned from source blocks.

If I execute the following source block:
#+begin_src python :results value
  return (1,2)
#+end_src

I get the following error message:
: Symbol's function definition is void: 1\,

The Python output for this source block is =(1,2)=, which =org-babel-read=
interprets as lisp and tries to eval.

I can work around the problem using either a Python list:
#+begin_src python :results value
  return [1,2]
#+end_src

or by using =:results output=
#+begin_src python :results output :session
  (1,2)
#+end_src

Regards,
Scott
