On reddit[1] loskutak-the-ptak pointed out that the manual states that the default value is not optional: [2] So it is not a bug and it was my own fault from the start. Default values might be omitted for non-string parameters but it is not backed by the documentation.

[O] org-sbe: error when passing strings as parameters to/from Python blocks
Hi! I want to test/use Python with org-sbe: #+NAME: classificationfm #+BEGIN_SRC python :exports none :var prob :var impact result = "" if prob == 'high' and impact == 'high': return 'A' if prob == 'low' and impact == 'high': return 'B' if prob == 'high' and impact == 'low': return 'C' if prob == 'low' and impact == 'low': return 'D' return 'undefined' #+END_SRC (Yes, I should move to elif and the Python code might be coded with less characters in general: this should not be the point here ;-) ) | prob | impact | class | |--++| | high | high | #ERROR | | low | high | #ERROR | | high | low| #ERROR | | low | low| #ERROR | #+TBLFM: @2$3..@>$3='(org-sbe "classificationfm" (prob $1) (impact $2)) I'd expect to get the values of the "class" table column: A, B, C, D instead of #ERROR. Reading the manual, I found: | NOTE: By default, string variable names are interpreted as | references to source-code blocks, to force interpretation of a | cell’s value as a string, prefix the identifier a "$" (e.g.,"$$2" | instead of "$2" or "$@2$2" instead of "@2$2"). Therefore, I tried the following lines ... #+TBLFM: @2$3..@>$3='(org-sbe "classificationfm" (prob "$1") (impact "$2")) #+TBLFM: @2$3..@>$3='(org-sbe "classificationfm" (prob $$1) (impact $$2)) #+TBLFM: @2$3..@>$3='(org-sbe "classificationfm" (prob "$$1") (impact "$$2")) ... all with same error in the result. My setup: Org mode version 9.1.6 on GNU Emacs 26.0.90 and GNU Emacs 25.1.1 I started a reddit thread[1]. In this thread, somebody was posting this table showing the error: #+NAME: myfunc #+BEGIN_SRC python :var n="1" return "ok" #+END_SRC | 10.3 | 9 | -18 | a | 14 | 11 | 1 | | ok | ok | ok | #ERROR | ok | ok | ok | #+TBLFM: @2='(org-sbe myfunc (n @1)) However, using the comment from the manual about strings, I prepended the reference with "$" ... | 10.3 | 9 | -18 | a | 14 | 11 | 1 | | ok | ok | ok | ok | ok | ok | ok | #+TBLFM: @2='(org-sbe mytestfunc (n $@1)) ... which now looks OK ;-) So, back to the initial situation: what is my error or do we have a bug in Org?
