import arcpy, os inSHP = r"C:\tmp\myShapefile.shp" #shapefile name featName = os.path.basename(inSHP) #build path to in_memory feature clas inMemoryFC = os.path.join("in_memory",featName[:-4]) arcpy.CopyFeatures_management(inSHP, inMemoryFC) #OPTIONAL - check featCount = int(arcpy.GetCount_management(inMemoryFC).getOutput(0)) print featCount
Some more notes on in_memory:
The in_memory workspace is only valid for geoprocessing tools; it is not a general-purpose virtual directory when you can write any data.
Clean up after using "in_memory" using Delete_management
For example,
Projects = os.path.join("in_memory","Projects") arcpy.MakeFeatureLayer_management(<pathToFC>,"Proj_lyr") arcpy.CopyFeatures_management("Proj_lyr",Projects) arcpy.Delete_management("Proj_lyr") print("Projects Copied")
