CreateScratchName example

Create a unique scratch name for the derived output of the Buffer tool. This scratch name is then used as input to the Clip tool.

import arcpy

# Set workspace
#
arcpy.env.workspace = "C:/Data/Municipal.gdb"

# Create a scratch name for the Buffer tool output.
#   The scratch name created will be include 'temp0.shp',
#   If temp0.shp already exists, the number will be incremented
#   until the name is unique in the workspace.
#
scratch_name = arcpy.CreateScratchName("temp",
                                       data_type="Shapefile",
                                       workspace=arcpy.env.scratchFolder)

# Execute Buffer tool, using scratch name for output
#
arcpy.Buffer_analysis("Roads", scratch_name, "1000 feet")

# Execute Clip tool, using scratch name for input
#
arcpy.Clip_analysis(scratch_name, "CityBoundary", "CityRoads")

# Delete scratch dataset
arcpy.Delete_management(scratch_name)
