This has been said before on numerous occations:

These delimiters do exist in python. Just do

for a in A:
  whatever
#endfor

The delimiters are very flexible. You may exclude them if you wish, as I
do, and you may spell them in many ways. Examples:

#end
#end for
#end for a
#ende
#slut
#fin
#rof

The interpreter simply disregards them since they do not carry any 
information.
