Cool, I did not find this parameter yet.

Is this undocumented? http://orgmode.org/org.html does not contain
the string ":python:" and
also does not mention this parameter.

Most interesting to me, thank you.

With the parameter above as a workaround, I can accomplish the
things I want to do for now. However, I still do think that Python2
and Python3 as different languages demand different block

#+BEGIN_SRC python -> defaults to the default python interpreter
#+BEGIN_SRC python2 -> uses Python2
#+BEGIN_SRC python3 -> uses Python3

Don't you think?
