Code: from supersetapiclient.client import SupersetClient

def rename_chart(slice_id, superset_client):
    try:
        chart = superset_client.charts.get(slice_id)
        print(chart)
    except:
        print(f"Chart with ID '{slice_id}' not found.")
        return

    new_name = f"TO BE DEPRECATED SOON - {chart.slice_name}"
    chart.slice_name = new_name

    chart.save()


if __name__ == "__main__":

    superset_client = SupersetClient(
        host="https://superset.X.net/",
        username="admin",
        password="",
    )

    chart_id_to_rename = 778  # Update this with the chart ID you want to test
    rename_chart(chart_id_to_rename, superset_client)
