problem with https://orgmode.org/manual/Results-of-Evaluation.html

[Uwe Brauer via General discussions about Org-mode.]

Hi 

I tried to use the examples of the above link

#+NAME: many-cols
| a | b | c |
|---+---+---|
| d | e | f |
|---+---+---|
| g | h | i |

#+NAME: no-hline
#+BEGIN_SRC python :var tab=many-cols :hlines no
  return tab
#+END_SRC

Now already the first failed:
,----
| 
|   File "<stdin>", line 4
|     return tab
|     ^
| IndentationError: unexpected indent
| [ Babel evaluation exited with code 1 ]
`----

Problem could be that which python on my Ubuntu system returns
Python 2.7.12

I presume the code is for python 3.X. How can I tell org to use that
one?

Regards

Uwe Brauer

No, this is because you customized `org-src-preserve-indentation' or
`org-edit-src-content-indentation', while the provided example only
works with default indentation settings. Python is sensitive to
whitespace and your config prevents Org mode from removing the two
spaces in the example block.

I adjusted the manual to not indent src blocks.  Then, they should work
across more wide range of user settings.

Handled.

Thanks, I confirm that 

#+NAME: many-cols
| a | b | c |
| d | e | f |
| g | h | i |

#+NAME: hline-please
#+BEGIN_SRC python :var tab=many-cols :hlines yes
return tab
#+END_SRC

#+RESULTS: hline-please
| a | b | c |
| d | e | f |
| g | h | i |

Works, but I also hoped that I could use python to add hlines to table
without hline, but alas it does not work!

:hlines controls filtering ---- from input. It does nothing about code
block output.

More specifically, ":hlines no" takes care about removing hlines from
the input. ":hlines yes" does not perform any filtering.

Ok understood, but then, who can I add hlines to table that does not
possess any?
