Creating the DAG

After setting the default arguments, it's time to define your DAG and create the first task that checks the API. This step is essential for automating your data and machine learning workflows. The following modules were imported: DAG, PythonOperator, and datetime. You also have a custom check_updates_api function available. Time to build your DAG!

交互式实操练习

通过完成这段示例代码来试试这个练习。

# Define the DAG
with ____(
    'data_pipeline',
    default_args=default_args,
    description='Data pipeline for ETL process',
  	# Set the schedule to run daily
    schedule='@____',
    tags = ["python", "etl", "forecast"]
) as dag:
  # Create check_api
  check_api = ____(
    task_id='check_api',
    # Use the check_updates_api function
    python_callable=____)

print(f"DAG object created: {dag}")
print(f"PythonOperator for API check created: {check_api}")
