how to quote "#+end_src" string in a Babel block?

how to quote "#+end_src" string in a Babel block?

[asenal]

Hi Guys I'm trying to do literature programming with org mode.
My problem is How can I safely quote "#+XXX" inside a Babel-block?
I found org-mode mismatch the outter "#+begin_src"  with the first "#+end_src" inside the block hence gives me a wrong parse.

Here's an example:
#+headers: :var varlist=top_iv
#+begin_src python :return iv_template(varlist)
  def iv_template(varlist,db,table):
      for var in varlist:
          babel_template='''
	  #+name: var
          #+begin_src sqlite :db mydb
            SELECT colName,cnt,suc,fal,iv FROM mytable WHERE colName == %s';
          #+end_src   # org mode stop here!
          ''' % (var,var)

          print babel_template
#+end_src

I know it looks twisted,but what I really care is wheather org-mode holds the capability to do so.

I don't know Python, but maybe you could do something like this

#+begin_src emacs-lisp :results value
(concat
  (format "%s%s %s\n\n" "\#+" "begin_src" "python")
  (format "%s%s" "\#+" "end_src"))
#+end_src

#+results:
: #+begin_src python
: 
: #+end_src

Within a source block, you must prepend a comma to every line starting
with "*" or "#+". C-c ' will do that for you.

The following syntax should work.  If you edit code blocks with C-' the
leading ' characters will be added and stripped automatically.

#+begin_src python :return iv_template(varlist)
  def iv_template(varlist,db,table):
      for var in varlist:
          babel_template='''
          ,#+name: var
          ,#+begin_src sqlite :db mydb
          SELECT colName,cnt,suc,fal,iv FROM mytable WHERE colName == %s';
          ,#+end_src   # org mode stop here!
          ''' % (var,var)
  
          print babel_template
#+end_src

Thank  for the answers .
I'm glad to know  ', ' is the right escaping character to quote '#+babel_statement'.

I apologize for answering so late.
