It would be much easier for people to help you if you would include the 
actual code you have written.
We have no way to tell you are running to the end or not; we certainly 
have nothing showing 'a best fit' algorithm. If we can see the actual 
code we can at least show you where you might want to look for current 
and/or potential problems.

Also, what OS are you using?
What version of Python are you using?
