from airflow.providers.standard.operators.bash import BashOperator

# A Dag represents a workflow, a collection of tasks
with DAG(dag_id="demo", start_date=datetime(2022, 1, 1), schedule="0 0 * * *") as dag:
# Tasks are represented as operators
with DAG(dag_id="demo", start_date=datetime(2022, 1, 1), schedule="0 0 * * *"):
# Tasks are defined by instantiating operators
hello = BashOperator(task_id="hello", bash_command="echo hello")

@task()
# Equivalent of BashOperator using the Airflow Taskflow syntax
@task.bash
def airflow():
print("airflow")
return "echo airflow"

@task
def world():
print("world")

# Set dependencies between tasks
hello >> airflow()
hello >> airflow() >> world()
