When you do an alt+e and select individual faces for extrusion in the Blender GUI, you can then either move your mouse around to move the extrusion up or down a path defined by the orientation of the normal of the source face.
Alternatively, I can hit alt+e, select individual faces and then on the number pad proceed to type in the exact value by which I would like the face to be extruded down this path, pressing RETURN to apply the transformation. I can then tap "s" and type a value by which I would like to scale the extruded face by a value I can type in, then again press RETURN to apply the transformation.
Now being a total blender python API/python noob, I'm wondering how I can accomplish this same result purely in python. I've already got a script that will iterate over all objects in my scene, select the face I would like extruded.... but now I need to know how I can extrude that individual face along the path of the normal (just like it would in the GUI) and of course scale it after, just as described above. Any help pointing me in the right direction would be greatly appreciated.
