This is a special case of non-linear fitting, which you can do with
the modules in ScientificPython. See
http://starship.python.net/~hinsen/ScientificPython/

Here is an extract from the relevant docs...

Module Scientific.Functions.LeastSquares

    * leastSquaresFit()

      General non-linear least-squares fit using the
Levenberg-Marquardt algorithm and automatic derivatives.
