Dalam contoh ini, skrip pekerjaan (MyTestGlueJob.py) ditulis dengan Python. Parameter Python ditentukan dalam $DefArgs variabel, dan kemudian diteruskan ke PowerShell perintah dalam DefaultArguments parameter, yang menerima hashtable. Parameter dalam $JobParams variabel berasal dari CreateJob API, didokumentasikan dalam topik Jobs (https://docs.aws.amazon.com/glue/latest/dg/ aws-glue-api-jobs -job.html) dari referensi AWS Glue API.
