Re: Bug: org-babel python with :results value sends function definition with a statement after a for loop to the shell incorrectly [9.3.6 (9.3.6-elpa @ /home/username/.emacs.d/elpa/org-9.3.6/)]

your example works for me without any changes. "return 42" works as well.
it returns None and there are no errors in the *bug_report* buffer.

I'm using:
GNU Emacs 25.2.2 (x86_64-pc-linux-gnu, GTK+ Version 3.22.21) of 2017-09-22,
modified by Debian
Org mode version 9.3.6 (release_9.3.6-739-g0c1740.dirty @
/home/ian/code/elisp/org-mode/lisp/)
