Jenkins Job scripts to generate packages in json file

Again, this is a script from the larger code that helps to accomplish the task above

This is the script:
jsonlist = json.dumps(packageL, indent=3) 
#print(jsonlist) 
open("packagelist.json", "w" ).write(jsonlist)

Format
{
   {
      "EAContextMenu.redist",
      "1.0.0.49"
   },
   {
      "mbcommon.redist",
      "3.2.0.845"
   },
   {
      "EAServiceMonitor.redist",
      "1.1.0.20"
   },
   {
      "BCrypt.Net",
      "0.1.0"
   },
  }
  
  {
  "Packages": [
    {
      "package_name": "EAContextMenu.redist",
      "package_ver": "1.0.0.49"
    },
    {
      "package_name": "mbcommon.redist",
      "package_ver": "3.2.0.845"
    },
    
  }
