body: <p>How to choose python version 3 while deploying AWS glue Job with glue version 1.0 using YAML(serverless)?
  I'm deploying AWS glue using serverless YAML code. AWS has provided GlueVersion parameter to choose the version of glue to use which I'm setting to '1.0'. I want to use Python 3 but it is deploying to python 2 in glue job. Does any have an idea how to set it to use python3 using YAML deployment code without manual changes in the glue job?</p>
