import arcpy
arcpy.env.workspace = "C:/MyData/Locators" 
arcpy.PackageLocator_management('Atlanta_composite', 'Altanta_composite.gcpk', "", "#","Summary of package","tag1; tag2; tag3")
PackageLocator example 2 (stand-alone Python script)

# Name:
# Description:  Find all the locators that reside in a specified folder and create a locator package for each locator.

# import system modules
import os
import arcpy

# Set environment settings
arcpy.env.overwriteOutput = True
arcpy.env.workspace = "C:/MyData/Locators" 

# Loop through the workspace, find all the locators and create a locator package using the same name as the locator.
for loc in arcpy.ListFiles("*.loc"):
    print("Packaging " + loc)
    arcpy.PackageLocator_management(loc, os.path.splitext(loc)[0] + '.gcpk', "", "#","Summary of package","tag1; tag2; tag3")
