The problem is that formatting as s-expression puts them into python code.

Here is what I want to do.

First edit a query string:
#+RESULTS: query
#+BEGIN_SRC sparql
   select *
   where { ?x rdf:label "x\\r"@en }
#+END_SRC

(The trick of naming this block with #+results: is so that:
   1. org-edit-src-code uses the right mode
   2. the code block is not evaluated
   3. its body is passed as a string to other code blocks.
For lack of a better idea...)

Use the query string verbatim in another language:
#+NAME: py
#+BEGIN_SRC python :var q=query
   # return some_graph.query(q)
   return q
#+END_SRC

But now calling py() or tangling would give a syntax error because
#+BEGIN_SRC elisp :var q=query
   (org-babel-python-var-to-python q)
#+END_SRC

#+RESULTS:
: ""#("select *
: where { ?x rdf:label \"x\\\\r\"@en }
: " 0 9 (face org-block font-lock-multiline t wrap-prefix #("  " 0 2 
(face org-indent)) line-prefix nil font-lock-fontified t fontified t) 9 
30 (face org-block font-lock-multiline t wrap-prefix #("  " 0 2 (face 
org-indent)) line-prefix nil font-lock-fontified t fontified t) 30 35 
(face org-block font-lock-multiline t font-lock-fontified t wrap-prefix 
#("  " 0 2 (face org-indent)) line-prefix nil fontified t) 35 40 (face 
org-block font-lock-multiline t font-lock-fontified t wrap-prefix #("  " 
0 2 (face org-indent)) line-prefix nil fontified t) 40 41 (face 
org-block font-lock-multiline t wrap-prefix #("  " 0 2 (face 
org-indent)) line-prefix nil font-lock-fontified t fontified t) 41 42 
(face org-block font-lock-multiline t wrap-prefix #("  " 0 2 (face 
org-indent)) line-prefix nil font-lock-fontified t fontified t))""

If org-babel-python-var-to-python does
#+BEGIN_SRC elisp :var q=query
   (format "%S" (substring-no-properties q))
#+END_SRC

#+RESULTS:
: "select *
: where { ?x rdf:label \"x\\\\r\"@en }
: "

then both evaluation and tangling work fine:
#+CALL: py()

#+RESULTS:
: select *
:     where { ?x rdf:label "x\\r"@en }


Best,
Daniel
