I am longtime Org user that only uses a few features of Org - mainly the ones here,
(info "(org)Document Structure")
and when I tried to explain in my tutorial how to execute org source blocks I stumbled on a behavior that I found very puzzling... I will copy the relevant code here. The section on preparation says to run these sexps,
but when I run the shell block with C-c C-c I get these errors
Error reading results: (user-error No table at point) Code block produced no output.
and an empty "#+RESULTS:" block in Emacs24, and the right results block in some later versions of Emacs, and when I run the Python block with C-c C-c I always get a results block like this (without the indentation):
#+RESULTS: : None
What am I doing wrong? I expected an output of "25"... =(
