Help PALIN (NZEC)

[cycy]

Hello all,

I try to resovle PALIN problem in PYTHON. But I get a NZEC status. I really don't know what is the meaning of this status? Is it a problem of wrong answers? Is it a problem of how to output answers?
As it is my first problem I am not sure to do the input/output correctly.
Is there anyone to help a desesperate guy?

Many thanks
Cyril

Thank you very much.
That's was very helpful.
But I am afraid that Python doesn't really like the recursive function when it iters quite a few time.
I will try to think to another way ... not easy.
I have to find a way to add 1 to a string without the for loop.

Thany you again
