Get List of manualy selected features on MXD and run script on selected features : [closed]

Question

Using arcgis 10.3, I trying to write code that when i do selection on layer manualy on MXD (not in the script) and run the script, the script need to run just on the selected features. I have tried -

layer = "Source Layer Path"
desc = arcpy.Describe(layer)
selected = desc.name
print (selected)

but it returns an empty list, is there a way to this in python?

I have tried this :

dataFrame = arcpy.mapping.ListDataFrames(Mxd)[0]
Layers=arcpy.mapping.ListLayers(Mxd, "", dataFrame)[0]
desc = arcpy.Describe(Layers)
selected = desc.Fidset
print ("selected = "+ str(selected))

Still same result

Answer 1

Your layer needs to refer to the layer in your MXD, not the path to the feature class.

layer = "Layer In MXD"
desc = arcpy.Describe(layer)
selected = desc.FIDSet
print (selected)

desc.Fidset will return the ObjectIDs of the selected features

---

mxd = arcpy.mapping.MapDocument("CURRENT")
dataFrame = arcpy.mapping.ListDataFrames(mxd)[0]

layers = arcpy.mapping.ListLayers(mxd, "", dataFrame)[0]

for layer in layers:
    desc = arcpy.Describe(layer) 
    selected = desc.FIDSet 
    print ("selected = "+ str(selected)) 

Answer 2

I find the answer : Need to do MakeFeatureLayer_management

dataFrame = arcpy.mapping.ListDataFrames(Mxd)[0]
Layers=arcpy.mapping.ListLayers(Mxd, "", dataFrame)[0]
for layer in dataFrame:
        Layers=arcpy.mapping.ListLayers(Mxd, "", dataFrame)[0]
        if Layers.name=="Signs":
            arcpy.MakeFeatureLayer_management(layer,"Signs_Shape_layer")
            desc = arcpy.Describe("Signs_Shape_layer")
            FID_selected = desc.FIDSet
            selected = FID_selected.split("; ")
            print (selected)
            break
