Fixing AttributeError: 'module' object has no attribute 'MakeRasterLayer_management'

Question

I'm trying to change my slope map's labels and colors to the specific ones I want which are shown in the code, but when I run this script it produces an AttributeError that doesn't make sense to me since I imported arcpy into my script.

Code:

def main():
 import arcpy
 from arcpy.sa import *
 arcpy.CheckOutExtension("Spatial")
 arcpy.env.workspace = "C:\\Users\\user\\OneDrive\\Documents\\ArcGIS\\ArcMap_Folder"
 inRaster = "USGS_13_n37w082_20220512.tif"
 outSlope = Slope(inRaster, "PERCENT_RISE")
 outSlope.save("C:\\Users\\user\\OneDrive\\Documents\\ArcGIS\\ArcMap_Folder\\slope2.tif")
 myRemapRange = RemapRange([[0, 3.99, 1], [4, 9.99, 2], [10, 15.99, 3], [16, 30.99, 4], [31, 60.99, 5], [61, 999999, 6]])
 outReclassRR = Reclassify(outSlope, "VALUE", myRemapRange,"NODATA" )
 outReclassRR.save("C:\\Users\\user\\OneDrive\\Documents\\ArcGIS\\ArcMap_Folder\\reclass2.tif")
 arcpy.management.MakeRasterLayer_management("outReclassRR", "outReclassRR_layer")
 arcpy.management.ApplySymbologyFromLayer(outReclassRR, reclass_copy.lyr)
if __name__ == '__main__':
 main()

Error:

Runtime error 
Traceback (most recent call last):
 File "<string>", line 24, in <module>
 File "<string>", line 17, in main

arcpy tools can either be used from their module or are aliased so they can be used from the top level.

From the management module:

arcpy.management.MakeRasterLayer

Or by the top-level alias:

arcpy.MakeRasterLayer_management

• Darell: Thanks! The first way worked for me! Apparently the "_management" section was what was causing the issue.
• user2856: @Darell no, arcpy.*management*.MakeRasterLayer_*management* is what won't work. arcpy.MakeRasterLayer_management will work as well as arcpy.management.MakeRasterLayer
• Darell: Ohh my bad, I read that wrong. Yes, that's true. arcpy.management.MakeRasterLayer is what worked for me.
