I tried using it like this: #+name: function-demo #+begin_src python :exports both :noweb yes :results output :no-expand <> =20 print entable([["One", 2, 59],["Four", 5, 27], ["Seven", 8, 9]]) #+end_src But it didn't seem to affect the results at all. I may be using it wrong, t= he documentation is a bit sparse, without any examples... It seems like I almost need some variant of the "tangle" argument to :noweb= where syntax references are expanded for evaluation, but not for anything = else.=20 Thanks for taking a look!
