Example (with single day):

weekend_check = DayOfWeekSensor(

    week_day='Saturday',
    use_task_logical_date=True,
    dag=dag)

weekend_check = DayOfWeekSensor(
    task_id='weekend_check',
    week_day={'Saturday', 'Sunday'},
    use_task_logical_date=True,
    dag=dag)

Example (with WeekDay enum):

# import WeekDay Enum
from airflow.utils.weekday import WeekDay

weekend_check = DayOfWeekSensor(
    task_id='weekend_check',
    week_day={WeekDay.SATURDAY, WeekDay.SUNDAY},
    use_task_logical_date=True,
    dag=dag)
