Explanation:
To create a managed table in Databricks using PySpark, you should use the DataFrame API. First, load your source data into a DataFrame (e.g., df = spark.table("source_table")), then write it as a managed table using df.write.saveAsTable("managed_table"). This method ensures Databricks manages both the data and metadata, and no location is specified, so the table is fully managed by Databricks.
