Hi Karl

Python2 and Python3 are two different languages. Unfortunately,
Org-mode only uses ~#+BEGIN_SRC python~ for both and uses
python-shell-interpreter to choose/switch the compiler.

Shouldn't Org-mode introduce ~#+BEGIN_SRC python2~ and ~#+BEGIN_SRC
python3~ to solve this issue in a clean way?

~#+BEGIN_SRC python~ can still default to python2.



You can use the :python header argument to the source block, which allows you to specify the path to the python interpreter:


————————— BEGIN EXAMPLE ———————— 

* Default python version
#+name: check-python-version
#+BEGIN_SRC python
import sys
return sys.version
#+END_SRC

#+RESULTS: check-python-version
: 3.4.4 |Anaconda 2.5.0 (x86_64)| (default, Jan  9 2016, 17:30:09) 
: [GCC 4.2.1 (Apple Inc. build 5577)]

This is the control experiment. 

* Custom python version
#+BEGIN_SRC python :python /Users/will/anaconda/envs/py27/bin/python
import sys
return sys.version
#+END_SRC

#+RESULTS:
: 2.7.11 |Continuum Analytics, Inc.| (default, Dec  6 2015, 18:57:58) 
: [GCC 4.2.1 (Apple Inc. build 5577)]

I only found those sources/solutions:

... workaround with #+srcname (I don't get yet)
