Using org-babel, the following example produces no output for me when I execute using C-c C-c:
#+begin_src python :results value
2 + 2
#+end_src
#+results:
: None
In my messages buffer I see the following:
: (Shell command succeeded with no output)
Now the equivalent emacs-lisp example does work:
#+begin_src emacs-lisp :results value
(+ 2 2)
#+end_src
#+results:
: 4
Furthermore,
#+begin_src python :results output
print(2 + 2)
#+end_src
#+results:
: 4
works as expected.
Am I missing something obvious? Is the problem with my python setup, or perhaps org-babel-python?
I have tested this on both my Windows and Ubuntu setups. I am using org version 6.34trans.
Cheers,
Scott

Or, if you are going to stick with the default non-session evaluation, you need to include a return statement: #+begin_src python :results value return 2 + 2 #+end_src #+results: : 4 This is explained in full at http://orgmode.org/worg/org-contrib/babel/reference.php#header-argument-results scroll down to the 2-by-2 table and the explanation below it.
