Write a code in Python given two spheres centered on points with coordinates (x1, y1 and z1) and (x2, y2 and z2) and radius r1 and r2, respectively, print one of the following message:

the spheres intersecting forming a circle of radius r0 where x0, y0 and z0 or r0 are values found by their code. (your code needs to calculate the radius of the circle formed)

Your code must work for all possible configurations
