Without any experience with Mathematica it would not be easy to do 
this.  It depends on how the function was written as a notebook or as a 
package, although you can turn the former into the latter and for your 
purposes probably want to.  Also there are two methods to access the 
kernel from external programs, Mathlink: a C interface which is 
probably easier from Python and J/Link a Java interface.  Finally again 
depending on the implementation the output may or may not be in a file.

I suggest 1) getting a copy of Mathematica and using the curve fit 
function from the notebook interface to get a feel for the Mathematica 
way of doing things.  This is also helpful in getting to step 2) 
writing some Mathlink or J/Link programs to interface with the curve 
fitting package (hopefully you have experience in calling external 
programs from Python).
