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/)]

Hello Philip,

I tested again and still can't reproduce the issue.  ob-python doesn't
change the indentation between individual lines of a code block, so this is
strange. Do you have the same issue if you aren't using a session? Are you
using tabs or spaces? (I tested with spaces)
