# FormatCase classe
<a name="aws-glue-api-pyspark-transforms-FormatCase"></a>

La trasformazione `FormatCase` modifica ogni stringa di una colonna applicando la formattazione specificata.

## Esempio
<a name="pyspark-FormatCase-examples"></a>

```
from pyspark.context import SparkContext
from pyspark.sql import SparkSession
from awsgluedi.transforms import *

sc = SparkContext()
spark = SparkSession(sc)

datasource1 = spark.read.json("s3://${BUCKET}/json/zips/raw/data")

try:
    df_output = data_cleaning.FormatCase.apply(
        data_frame=datasource1,
        spark_context=sc,
        source_column="city",
        case_type="LOWER"
    )    
except:
    print("Unexpected Error happened ")
    raise
```

## Output
<a name="pyspark-FormatCase-output"></a>

 La trasformazione `FormatCase` convertirà i valori nella colonna `city` in lettere minuscole in base al parametro `case\_type=“LOWER”`. Il `df\_output` risultante DataFrame conterrà tutte le colonne dell'originale `datasource1`, ma con i valori della colonna DataFrame `city` in minuscolo.

## \_\_call\_\_(spark\_context, data\_frame, source\_column, case\_type)
<a name="aws-glue-api-pyspark-transforms-FormatCase-__call__"></a>

La trasformazione `FormatCase` modifica ogni stringa di una colonna applicando la formattazione specificata.
+ `source_column`: il nome di una colonna esistente.
+ `case_type`: i tipi di formattazione supportati sono `CAPITAL`, `LOWER`, `UPPER`, `SENTENCE`.
