Wish: babel for python3

Wish: babel for python3

[Arne Babenhauserheide]

Hi, 

I’d love to have babel for python3. 

My first shot at it would just be ob-python.el with each mention of python replaced by python3, but I hope that there is a more elegant way… 

Is there a way to get python3 support for Babel into org-mode cleanly?

Best wishes, 
Arne

Hi Arne,

I think you can simply add the following to your configuration to use
python3 as your python executable.

  (setq org-babel-python-command "python3")

Hi Eric, 

Can I then still use babel for python 2.x? I need it for both, because I have 
python3 and python2 projects. 

Best wishes, 
Arne

Aloha Arne,

If your projects are in different files, then you should be able to use
file variables:
http://www.gnu.org/s/libtool/manual/emacs/Specifying-File-Variables.html#Specifying-File-Variables.

Something like:
-*- org-babel-python-command: "python3"

hth,
Tom

It works! Many thanks (this is damn cool!)

# -*- org-babel-python-command: "python3"; -*-

Hi,
(sorry Arne for the eventual double post, I forogot to attt the mailing 
list)

alternatively (a trick Eric is never tired to mention to me ) you could 
add a little lisp block which change all kind of language related 
aspects for you. This could include many more options and modify your 
emacs environment just to your personal needs for a certain language.

Make one for python2 and one for python3 and execute them dependent on 
which system you are going to use.

Without testing and without guarantee it should be something like the 
below code. To demonstrate some more functionality lets change the 
modebar background colour to make it more visible which python mode you 
are currently using.


#+srcname: python2_env
#+begin_src emacs-lisp
  (setq org-babel-python-command "python")
  (set-face-background 'modeline "#4477aa")
#+end_src

#+srcname: python3_env
#+begin_src emacs-lisp
  (setq org-babel-python-command "python3")
  (set-face-background 'modeline "#771944")
#+end_src

Sure both could be done with file bounded variables too. But know you 
can switch between both environments within the same buffer, e.g., to 
check if the code runs on both python versions

That is pure awesomeness!  

Thanks,
