If you want to access Glue catalog tables inside a python shell job then you can leverage aws-data-wrangler library.Refer to this on how you can import it into your python shell job.

Also this and this has more examples on how you can read tables from Glue catalog.Below is a simple example that you can use to achieve this:

dtype = wr.catalog.get_table_types(database="awswrangler_test", table="csv_crawler")

df = wr.athena.read_sql_table(database="awswrangler_test", table="csv_crawler")
