Python and C

[hermes at numericable.fr]

Hi, this may be a newbie question, as I'm quite new to python but I'd rather get
your points of view instead of wasting a week or two on a wrong way 

I'm using python 2.3 on a mandrake brand new system 

My problem : I'd like to use a complex C program under python. 
After few researchs I tested SWIG, which seems to work for me exept that I'd
like to be able to 
use a C function under python that has this prototype 

void Fitimp(double *x1, double *x2... ) 

these double parameters are lists of double precision number.
The python script will read this datas from files, So i'd like to know how to
transform a python list of double precision float to a C double * variable

Thx for your help
