Actually things now seem to be working. All cases. No hanging when I run Python in a session, and return and print work when running IPython. I wrote a test example, load it with emacs -q and then load a minimal org setup in a code block (I think I'm just starting to get the hang of some basic lisp and tangling code in Org). I've tried all possible cases (yes/no session, and results of default/output/value) and it all seems to be working. I then repeated it all with IPython instead of default Python. Output results are a bit ugly when using IPython. If I get a chance I'll look into the code. Since regular python output doesn't print the startup info, I assume the same can be done for IPython. It should just ignore everything until the first In [1]: text appears. Perhaps the previous issues were due to a complicated org setup. Test file follows.

Re: [O] python :session does return
Hi John,
Yes, you and others in that thread seem to be experiencing the same
problem, although there are also different issues discussed there.
I'm a bit surprised... With the popularity of python I would expect more
org users to have run into this and it to be fixed, but perhaps it isn't as
widely used as I thought. Anyway, it is now usable even if the 'print'
statements don't show up.
-k.

Emacs hangs the first time with minibuffer message of Sent

Re: [O] python :session does return
I think the issue here is that python users seem less likely (per user
on average) to edit the related Org-mode support (i.e., ob-python.el)
than users of some other languages which may be less popular in the
large but have better Org-mode support.
Also, as a maintainer of Org-mode's code block support, I personally do
not use Python.
Best,

I believe that's the expected behaviour: the defaults value of :results
for python (and most other) source blocks is value and the print statement
has no
value. If you want the output to appear in the results, try :results output.

Nope. If I don't use IPython, everything hangs regardless of :results.
When I do use IPython, :results output doesn't show print statement.
The plain x showing up in the output goes away if I use :results output.

Emacs hangs the first time with minibuffer message of Sent
python-eldoc-setup-code. If I C-g, I can edit the org buffer again.
All
other invocations of that code and the minibuffer message is executing
Python code block..., but still emacs hangs until I C-g.
Hmm. If I run IPython instead of regular python by setting this:
(setq org-babel-python-command ipython --pylab --pdb --nosep)
Then org does not hang. It returns as expected.
In Org, the following:
#+begin_src python :session foo
x = 42
print x
#+end_src
Produces no RESULTS, and in the Python *foo* buffer I see:
In [8]: x = 42
In [9]: print x
42
In [10]:
open('/var/folders/60/jb7kfrsn2jd90hpcgj4m_wrcgn/T/babel-35562TZV/python-3$
In [11]: 'org_babel_python_eoe'
Out[11]: 'org_babel_python_eoe'
But if I remove the print statment in Org:
#+begin_src python :session foo
x = 42
x
#+end_src
Then the RESULTS shows me 42, and the Python *foo* buffer is:
In [12]: x = 42
In [13]: x
Out[13]: 42
In [14]:
open('/var/folders/60/jb7kfrsn2jd90hpcgj4m_wrcgn/T/babel-35562TZV/python-3$
In [15]: 'org_babel_python_eoe'
In [15]: Out[15]: 'org_babel_python_eoe'
I believe that's the expected behaviour: the defaults value of :results
for python (and most other) source blocks is value and the print
statement has no
value. If you want the output to appear in the results, try :results
output.
Nope. If I don't use IPython, everything hangs regardless of :results.
When I do use IPython, :results output doesn't show print statement.
The plain x showing up in the output goes away if I use :results output.
I'm not talking about the hang: that's a problem (although I can't
reproduce it, so it may -or may not - be a problem with your particular
setup.)
I was specifically addressing this comment:
However, the capturing of output doesn't seem to work right.

I've seen various historical issues with :session but it seems I may have a
different problem. This is the latest org in emacs 24.3. If I do not have
:session, then everything works just fine.
This sounded familiar to me, so I googled around for Org mailing list
discussions I was involved in related to python. Does this shed any
new light?
- https://www.mail-archive.com/emacs-orgmode@gnu.org/msg68542.html
Seems that the discussion ended with the possibility that it was an
emacs change to python.el, and not related to Org, but I'm not sure if
any actions were ever taken regarding that. In any case, the
discussion features a discrepancy between python behavior with
`:session name` and without, so it seemed like a possible candidate to
pass along!

If I C-c C-c in the following code:
#+BEGIN_SRC python :session transect
import numpy as np
x = np.arange(12)
#+END_SRC
Emacs hangs the first time with minibuffer message of Sent
python-eldoc-setup-code. If I C-g, I can edit the org buffer again. All
other invocations of that code and the minibuffer message is executing
Python code block..., but still emacs hangs until I C-g.
If I look at the *transect* buffer, I see the following. The code runs just
fine, but for some reason it does not return.
-k.
