Unexpected Behavior with arcpy.addDataFromPath

Arne_Gelfert

Working on a work-around for another conundrum and tried the following:

 

import arcpy

x = some X
y = some Y

point = arcpy.Point(x,y)

ptGeometry = arcpy.PointGeometry(point)

feature_class = arcpy.CreateFeatureclass_management("in_memory", "tempfc", "POINT")[0]

with arcpy.da.InsertCursor(feature_class, ["SHAPE@XY"]) as cursor:
    cursor.insertRow(ptGeometry)

aprx = arcpy.mp.ArcGISProject("CURRENT")
symbologyLayer = r"<some path>...\someSymbology.lyrx"

arcpy.management.ApplySymbologyFromLayer(feature_class,symbologyLayer)

# Interestingly, the following works too
#arcpy.ApplySymbologyFromLayer_management(feature_class,symbologyLayer)

map = aprx.listMaps()[0]
map.addDataFromPath(feature_class)

‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

So this works great in that I'm getting a symbol plotted where I needed. But it does that three (3)  times giving me the following output.

 

Now, I realize I could try and control the place of insertion by using addLayer() and using the LYRX file directly after updating its data source. But the above output is not what I would expect based on what I'm doing. What's going on there?

Regarding these lines:

arcpy<SPAN class="punctuation token">.</SPAN>management<SPAN class="punctuation token">.</SPAN>ApplySymbologyFromLayer<SPAN class="punctuation token">(</SPAN>feature_class<SPAN class="punctuation token">,</SPAN>symbologyLayer<SPAN class="punctuation token">)</SPAN>

<SPAN class="comment token"># Interestingly, the following works too</SPAN>
<SPAN class="comment token">#arcpy.ApplySymbologyFromLayer_management(feature_class,symbologyLayer)</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

Line #01 and Line #04 call the exact same geoprocessing tool, so you should expect them to both work.  Line #01 represents the new syntax that Esri is pushing with Pro while Line #04 represents the original/legacy syntax.

The default for arcpy.env.addOutputsToMap is True, and I am guessing you are using the defaults, so lines #10, #18, and #24 in your code snippet will all add layers to the TOC, which is what you are seeing.
