Using org-babel, the following example produces no output for me

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.

Hi Scott,
You need :session.
#+begin_src python :session :results value
2 + 2
#+end_src
#+results:
: 4
