# IsEven class
<a name="aws-glue-api-pyspark-transforms-IsEven"></a>

 The `IsEven` transform returns a Boolean value in a new column that indicates whether the source column or value is even. If the source column or value is a decimal, the result is false. 

## Example
<a name="pyspark-IsEven-examples"></a>

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

sc = SparkContext()
spark = SparkSession(sc)

input_df = spark.createDataFrame(
    [(5,), (0,), (-1,), (2,), (None,)],
    ["source_column"],
)

try:
    df_output = math_functions.IsEven.apply(
        data_frame=input_df,
        spark_context=sc,
        source_column="source_column",
        target_column="target_column",
        value=None,
        true_string="Even",
        false_string="Not even",
    )
    df_output.show()
except:
    print("Unexpected Error happened ")
    raise
```

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

 The output will be: 

```
```
+------------+------------+
|source_column|target_column|
+------------+------------+
| 5| Not even|
| 0| Even|
| -1| Not even|
| 2| Even|
| null| null|
+------------+------------+
```
```

 The `IsEven` transformation takes the `source\$1column` as "source\$1column" and the `target\$1column` as "target\$1column". It checks if the value in the `"source\$1column"` is even or not. If the value is even, it sets the `"target\$1column"` value to the `true\$1string` "Even". If the value is odd, it sets the `"target\$1column"` value to the `false\$1string` "Not even". If the `"source\$1column"` value is `null`, the `"target\$1column"` value is set to `null`. 

 The transformation correctly identifies the even numbers (0 and 2) and sets the `"target\$1column"` value to "Even". For odd numbers (5 and -1), it sets the `"target\$1column"` value to "Not even". For the `null` value in `"source\$1column"`, the `"target\$1column"` value is set to `null`.

 The `IsEven` transform returns a Boolean value in a new column that indicates whether the source column or value is even. If the source column or value is a decimal, the result is false. 
+ `source_column` – The name of an existing column.
+ `target_column` – The name of the new column to be created.
+ `true_string` – A string that indicates whether the value is even.
+ `false_string` – A string that indicates whether the value is not even.
