You can use the set_keep_job_flow_alive_when_no_steps to configure a cluster (job flow) to terminate after the step execution, i.e., all your steps are executed. If you want a transient cluster that shuts down after the last of the current executing steps are completed, you can configure set_keep_job_flow_alive_when_no_steps to false. If you want a long running cluster, configure set_keep_job_flow_alive_when_no_steps to true.
