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

 La trasformazione `MonthName` crea una nuova colonna che contiene il nome del mese, a partire da una stringa che rappresenta una data. 

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

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

sc = SparkContext()
spark = SparkSession(sc)

spark.conf.set("spark.sql.legacy.timeParserPolicy", "LEGACY")

input_df = spark.createDataFrame(
    [
        ("20-2018-12",),
        ("2018-20-12",),
        ("20182012",),
        ("12202018",),
        ("20122018",),
        ("20-12-2018",),
        ("12/20/2018",),
        ("02/02/02",),
        ("02 02 2009",),
        ("02/02/2009",),
        ("August/02/2009",),
        ("02/june/2009",),
        ("02/2020/june",),
        ("2013-02-21 06:35:45.658505",),
        ("August 02 2009",),
        ("2013/02/21",),
        (None,),
    ],
    ["column_1"],
)

try:
    df_output = datetime_functions.MonthName.apply(
        data_frame=input_df,
        spark_context=sc,
        source_column="column_1",
        target_column="target_column"
    )
    df_output.show()
except:
    print("Unexpected Error happened ")
    raise
```

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

 L'output sarà: 

```
```
+------------+------------+
| column_1|target_column|
+------------+------------+
|20-2018-12 | December |
|2018-20-12 | null |

```
```

 La trasformazione `MonthName` assegna `source\$1column` come `“column\$11”` e `target\$1column` come `“target\$1column”`. Tenta di estrarre il nome del mese dalle date/time stringhe nella colonna `"column\$11"` e lo colloca nella colonna `"target\$1column"`. Se la date/time stringa è in un formato non riconosciuto o non può essere analizzata, il valore `"target\$1column"` è impostato su `null`. 

 La trasformazione estrae correttamente il nome del mese da vari date/time formati, come «20-12-2018", «20/12/2018", «02/02/2009", «2013-02-21 06:35:45.658 505" e «02 agosto 2009".

 La trasformazione `MonthName` crea una nuova colonna che contiene il nome del mese, a partire da una stringa che rappresenta una data. 
+ `source_column`: il nome di una colonna esistente.
+ `value`: una stringa di caratteri da valutare.
+ `target_column`: un nome per la nuova colonna creata.
