How to add Symbology to a Feature Class??

Question

I don't understand how to add a simple symbology to a feature class created in the the script and add it to a new map. Well I kind od did figure it out but this my code seems ridiculously long just to add symbology from a existing layer. I thought up to line 21 would be good enough to set the symbology I need. However, i had to add line 22,23,24 to get what I want. Basically I want the user to enter in a feature class, set a SQL expression and isolate the feature they want. Take that feature save it, add it to a different mxd, apply the symbology from an existing layer and save the mxd. I've heard of Derived and SetOutputParameters and apply the symbology there but I dont understand how to write that in the code. import arcpy, datetime, os, sys, string date = datetime.datetime.now() namefile = arcpy.GetParameterAsText(0) prjbdy = arcpy.GetParameterAsText(1) express = arcpy.GetParameterAsText(2) mxdpath = "C:\Users\Adam\Desktop\Test5.mxd" arcpy.CreateFileGDB_management(namefile, "\SlopeAdam" + date.strftime("%Y%m%d")+ ".gdb") fgdb = namefile + "\Slope" + date.strftime("%Y%m%d")+ ".gdb" arcpy.env.workspace = fgdb mxd = arcpy.mapping.MapDocument(mxdpath) df = arcpy.mapping.ListDataFrames(mxd)[0] arcpy.MakeFeatureLayer_management(prjbdy, "prjbdy_Layer",express) arcpy.CopyFeatures_management("prjbdy_Layer", "test3") arcpy.MakeFeatureLayer_management("test3", "test4") arcpy.ApplySymbologyFromLayer_management('test4', "C:\Users\Adam\Desktop\SlopeAnalysis\prjbdy_Layer.lyr") arcpy.SaveToLayerFile_management('test4',"C:\Users\Adam\Desktop\SlopeAnalysis\prjbdyoutada") addLayer = arcpy.mapping.Layer('test4') arcpy.mapping.AddLayer(df, addLayer, "AUTO_ARRANGE") arcpy.AddMessage("Finished Adding raster & applying symbology.") mxd.save() del mxd‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Thanks!

Yes Dan,

I usually do, but i guess i forgot.

And yes I'm using 2.7 and arcmap 10.5.1

Thanks,

That issue aside, must be arcmap and python 2.7 because it throws an error because your paths aren't raw encoded, in python 3. Not a bad idea even in 2.7 "C:\Users\Adam\Desktop\SlopeAnalysis\prjbdy_Layer.lyr" File "", line 1 "C:\Users\Adam\Desktop\SlopeAnalysis\prjbdy_Layer.lyr" ^ SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape r"C:\Users\Adam\Desktop\SlopeAnalysis\prjbdy_Layer.lyr" 'C:\Users\Adam\Desktop\SlopeAnalysis\prjbdy_Layer.lyr'‍‍‍‍‍‍‍‍‍
