This use of :prologue appeared to me to be very useful.  But for some reason when I try it out it does not work for me.  I just get a message that the code block produced no output and that 'np' is not defined.  Just to check, when I put the import statements directly within my code block it works fine.

I am running:  Org mode version 9.3.7 (9.3.7-16-g521d7f-elpa

Any idea what I'm doing wrong?

Actual example:

* Prologue test
:header-args:python+: :prologue "import numpy as np; import os"

#+BEGIN_SRC python :results output

What about using :pre or :prologue and setting it at the header or document level?

Use case:

I'm using ob-racket but this would apply just as well to a few other workflows I have with python or js.

I would like to write a helper function in a src block and then automatically have access to it in other src blocks further down the document. I don't really want a stateful session (nor does ob-racket support sessions) so I essentially want the equivalent of automatically including it everywhere so I don't have to type it out all the time (and have it screw up syntax coloring/indentation).

Is this currently possible? Does anyone have any ideas for how to extend things so it is?
