How to create a parametric surface in python?

in python,i would like to write the following script:

import bpy

import math

x=R*(1-u/(100*pi))*cos(u)*cos(v)

y=R*(1-u/(100*pi))*sin(u)*sin(v)

z=R*u/(100*pi)*v

where u varies from 0 to 1000*pi and v varies from for example 0 to 50*pi

In this script, what should I add as lines to create this surface ?

thanks
