I am very new to Python and trying to project many raster files using arcpy. Here is the screenshot of my raster files.

These raster files have an unknown coordinate system but I can project them with "ProjectRaster" in ArcGIS pro using 'GCS_WGS_1984'. I looked several online examples and revise one of them but could not work. Here is my scripts.

import acrpy

import os 

arcpy.env.workspace = "D:/STAR/assignment/assignment7/info_data_test" #The 

file where your files are

arcpy.env.overwriteOutput = True

outWorkspace = "D:/STAR/assignment/assignment7/info_data_test_results" #where 

you want the new rasters to go

arcpy.env.parallelProcessingFactor = "50"

rasters = arcpy.ListRasters()



#Begin loop



for inrl in rasters:



# Determine if the input has a defined coordinate system, can't project it if 

it does not

dsc = arcpy.Describe(inrl)



if dsc.spatialReference.Name == "Unknown":

    # Determine the new output feature class path and name

    outrl = os.path.join(outWorkspace, inrl)



    # Set output coordinate system

    outCS = arcpy.SpatialReference('GCS_WGS_1984')



    # run project tool

    arcpy.AddMessage("Reprojecting" + inrl)

    arcpy.Project_management(inrl, outrl, outCS)



    # check messages

    print(arcpy.GetMessages())



else:



    print ('skipped this raster file: ' + inrl)



    print(arcpy.AddMessage("Reprojection complete"))



    print "Script run ok"

When I ran this script, there appear mistakes. Here is the screenshot of error information.
