Im generating cubes with this code:

for a in range(10): x = random.randint(-5, 4) y = random.randint(-2, 7) z = random.randint(3, 10) bpy.ops.mesh.primitive_cube_add(location=(x,y,z), radius = 1)

What do I add to make sure no one of these 10 cubes are created with some part of it inside of one of the earlier created cubes?
