Error with UpdateCursor: Object does not support data assignment?

Question

I have a field for aspect (short integer) with values ranging from 1-4. I want to have 3 additional columns: aspect2, aspect3, aspect4 that are calculated based on the aspect field (for example, if the aspect field is 2, then aspect2 = 1, aspect3 =0 and aspect4 =0). Here is the code I have: arcpy.AddField_management(input, 'aspect2', 'SHORT') arcpy.AddField_management(input, 'aspect3', 'SHORT') arcpy.AddField_management(input, 'aspect4', 'SHORT') with arcpy.da.UpdateCursor(input, ['aspect', 'aspect2', 'aspect3', 'aspect4']) as cursor: for row in cursor: if cursor[0] == 2: cursor[1] = 1 cursor[2] = 0 cursor[3] = 0 cursor.updateRow(row) elif cursor[0] == 3: cursor[1] = 0 cursor[2] = 1 cursor[3] = 0 cursor.updateRow(row) elif cursor[0] == 4: cursor[1] = 0 cursor[2] = 0 cursor[3] = 1 cursor.updateRow(row) else: cursor[1] = 0 cursor[2] = 0 cursor[3] = 0 cursor.updateRow(row)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ When I run it, I get the following error: Traceback (most recent call last): File "", line 19, in TypeError: 'da.UpdateCursor' object does not support item assignment I'm not sure if it's a basic syntax issue (it's very possible) or I'm not thinking about it correctly. Any ideas are greatly appreciated.
