Airflow dag automatically Triggers

I have created the dag with the following configuration

job_type='daily'
SOURCE_PATH='/home/ubuntu/daily_data'

with DAG(
    dag_id="transformer_daily_v1",
    is_paused_upon_creation=False,
    default_args=default_args,
    description="transformer to insert data",
    start_date=datetime(2022,9,20),
    schedule_interval='31 12 * * *',
    catchup=False
) as dag:
    task1=PythonOperator(
        task_id="dag_task_1",
        python_callable=get_to_know_details(job_type,SOURCE_PATH),
    )

def get_to_know_details(job_type,SOURCE_PATH):
     print("************************",job_type,SOURCE_PATH)

Each time when i start the airflow using command

airflow standalone

the dag function executed automatically without Triggering as seen in the logs
