Get uniqe data source list from ArcGIS Pro project

Question

How to get distinct data sources of layers and tables in ArcGIS Pro project?

    aprx = arcpy.mp.ArcGISProject("CURRENT")
    maps = aprx.listMaps()
    for map in maps:
        print ('--------------------------------------------------------------')
        print (map.name)
        print ('--------------------------------------------------------------')
        layers = map.listLayers()
        tables = map.listTables()
        for layer in layers:
          print (layer.dataSource)
        for table in tables:
          print (table.dataSource)

Answer 1

List layer objects, extract their sources using dataSource property, convert to a set which can't have duplicates:

import arcpy

aprx = arcpy.mp.ArcGISProject("CURRENT")

layers = [] #A list to hold layer objects

for mp in aprx.listMaps(): #For each map in the project
    for layer in mp.listLayers(): #Find all layers
        layers.append(layer)
    for table in mp.listTables(): #And tables
        layers.append(table)
        
sources = [x.dataSource for x in layers] #Extract their sources
print(set(sources)) #Print unique sources
