    process_function = {'TOLOWER' : process_lower_function }
    spark = SparkSession.builder.master("local[1]").appName('intelligent').getOrCreate()
    data = [(0, "cards"), (1, "upper")]
    deptColumns = ["index", "data"]
    df = spark.createDataFrame(data=data, schema = deptColumns)
    print (df.show())

            logging.info(f"LOWER :: {text} -- {rule}")
    print (text)
    return text
