Thanks for your concern Wesley..
Yes.. by "screen" I meant "browser"
As I had said in my first message, printing the 0 on browser isn't my
objective. I am actually write services in which I just get the input,
process it and send the processed output in JSON format. So, in this I
do not need to write anything on the browser using "server side
script".
But the thing is, the code I wrote didn't work and I needed it debug
it by writing each and every relevant thing on the browser. And
printing that zero comes here..
I tried something like self.response.out.write(str(0)) and 0 is there
on the screen.. but I generally do not need to do this with any other
value.. let it be a python list or dictionary.. so I'm just not able
to know the reason or logic behind this..
By the way, a good news.. ! That service for which I was writing that
code is done. It's working.. :) But that cofusion of mine is still
intact.. :(
"why" that zero is not coming?
Thanks,
Chirag S Pithadiya.
