The key thing is, it's functional, not procedural. Instead of a sequence of
statements performing actions, it uses expressions that compute values.

Here's another one (from <http://github.com/ldo/linear2d/tree>):

def MapRect(SrcRect, DstRect) :
    """returns a Matrix that does appropriate scaling and translation
    to map the corners of SrcRect to DstRect."""
    return \
      (
            Matrix.translation(- SrcRect.topleft())
        *
            Matrix.scaling(DstRect.dimensions() / SrcRect.dimensions())
        *
            Matrix.translation(DstRect.topleft())
      )
#end MapRect
