------------------------------------------

Is spark__partition__id available in PySpark too? Can't find a way to run the same code in PySpark.

> Create the infrastructure so we can resolve df("SPARK__PARTITION__ID") to SparkPartitionID expression.

> {code}
> df.groupBy("SPARK__PARTITION__ID").count()
> {code}
