Hi Karl

On Sun, May 8, 2016 at 3:31 AM, Karl Voit <devnull@karl-voit.at<= /a>> wrote:

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.








I only found those sources/solutions:

... file-variables to choose interpretor

http://thread.gmane.org/gmane.emacs.orgmode/47867
... workaround with #+srcname (I don't get yet)
