I'm trying to list all active clusters on EMR using boto3 but my code doesn't seem to be working it just returns null.

Im trying to do this using boto3

1) list all Active EMR clusters

```
aws emr list-clusters --active

```

2) List only Cluster id's and Names of the Active one's
**cluster names**

```
aws emr list-clusters --active --query "Clusters[*].{Name:Name}" --output text

```

**Cluster id's**

```
aws emr list-clusters --active --query "Clusters[*].{ClusterId:Id}" --output text

```

But i'm blocked in the starting stage of using boto3

```
import boto3
client = boto3.client("emr")
response = client.list_clusters(
    ClusterStates=[
        'STARTING',
    ],
)

print response

```

Any suggestions how can i convert those CLI commands to boto3 

Thanks
