We don;t do homework here but we can help with specific
questions and to resolve errors.

OK, this is so far off base that I have to ask whether you
have done any Python programming at all before? Where is
this assignment (which I asume it is?) coming from? It seems
kind of unfair to ask you to do this if you haven't even covered
the basics of Python already!

Calling python's square root function won't do anything for
implementing Newtons methiod, except maybe prove the
result when you get there is close...

Can you give us a bit more background to where this
challenge is coming from and your bbackground, otherwise
I'd say you need to go through one of the beginners tutorials.
There are many on the Python web site, pick one that looks
good to you.

HTH,
