Using = org-babel, the following example produces no output for me when I = execute using C-c C-c:

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

hth,
