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)]
————————— END EXAMPLE ————————
