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

`FormatCase` 변환은 열의 각 문자열을 지정된 케이스 유형으로 변경합니다.

## 예제
<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
```

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

 `FormatCase` 변환은 `case\$1type="LOWER"` 파라미터를 기반으로 `city` 열의 값을 소문자로 변환합니다. 결과 `df\$1output` DataFrame에는 원래 `datasource1` DataFrame의 모든 열이 포함되지만 `city` 열 값은 소문자로 표시됩니다.

`FormatCase` 변환은 열의 각 문자열을 지정된 케이스 유형으로 변경합니다.
+ `source_column` – 기존 열의 이름입니다.
+ `case_type` – 지원되는 케이스 유형은 `CAPITAL`, `LOWER`, `UPPER`, `SENTENCE`입니다.
