To distinguish whether an input is a raster as opposed to a scalar variable, the input raster is cast using the Raster class: Raster("inRas").
In operators that accept two inputs, if both inputs are scalars, the Python operator will be used working on scalars. If one or both of the inputs are rasters (identified by casting with the Raster class), the Spatial Analyst operator is used and will work on each cell within the rasters. For those operators that accept a single input, if it is a scalar, then the Python operator is used; if a raster is input, the Spatial Analyst operator is used.
