Unable to loop through rasters to extract by mask

[KathleenHoenke]

I am trying to loop through several rasters and use them as the mask to extract from one large source raster. This script works well but only outputs one output for the first raster in the workspace. I've tried multiple things, but nothing seems to work. Thank you!

print (HR_FloodplainBounds_rasters)

    clipping_fc_path = os.path.join(HR_FloodplainBounds_fgdb, 
    HR_FloodplainBounds_raster)
    out_raster_name = "NLCD19" + HR_FloodplainBounds_raster
    arcpy.env.mask = clipping_fc_path
    arcpy.env.snapRaster = clipping_fc_path

    OutExtractByMask.save(out_raster_path)

Reviewing your code, it looks like it should work, although you have unnecessary code within the loop. What does the line print (HR_FloodplainBounds_rasters) return?

I figured it out .. ExtractByMask.save needs to be ExtractByMask.Save, with a capital S. Ulgh!
