How to calculate multiple equations (a+bX+cY+dZ), where (a, b, and c) are regression coeficients and (X, Y and Z) are rasters, using Pyton?

I need to run 252 equations to calculate freeze probability using lat, lon, and altitude as raster inputs, multiplied by a, b, c and d regression coeficients. The equations are in format a+b*lat+c*lon+d*alt.


The equations are in an Excel spreedsheet (attached) and I need to write them in a python script. The lat, lon and lat raster datasets are in the same folder and the output tif files have a standardized name (also in the Excel file).


Thank you!
