nonlinear least square

[Dmitry Rozmanov]

Hi.

I am looking for simple and convenient way to do nonlinear least square 
fit from within Python.

I know that there are such a modules in Scientific Python and SciPy has 
it. But I would like to have it small and simple. Module with just this 
functionality. It can be not very fast, but in pure python for beter 
compatibility.

Can you recommend such a module?

Thank you in advance.

Regards.
