1fill in blank

easy

Complete the code to retrieve a secret value using Airflow's Variable API.

Apache Airflow

from airflow.models import Variable

api_key = Variable.get([1])

Drag options to blanks, or click blank then click option'

BAPI_KEY

C"api_key"

Dapi_key

💡 Hint

Common Mistakes

Forgetting to put quotes around the secret name

Using variable names without quotes

You must pass the secret name as a string to Variable.get(). Using quotes ensures it is treated as a string key.

medium

Complete the code to set a default value when retrieving a secret that might not exist.

Apache Airflow

from airflow.models import Variable

password = Variable.get('DB_PASSWORD', [1]='default_pass')

Drag options to blanks, or click blank then click option'

Adefault

Bdefault_var=True

Cdefault_var='default_pass'

Ddefault_var

💡 Hint

Common Mistakes

Using 'default' instead of 'default_var'

Not assigning the default value as a string

The correct parameter to set a default value is default_var with the desired default string.

3fill in blank

hard

Fix the error in the code to correctly fetch a secret from Airflow's connection backend.

Apache Airflow

from airflow.hooks.base import BaseHook

conn = BaseHook.get_connection([1])
print(conn.password)

Drag options to blanks, or click blank then click option'

Amy_conn_id

B'my_conn_id'

Cmy_conn_id()

D"my_conn_id"

💡 Hint

Common Mistakes

Passing the connection ID without quotes

Calling the connection ID as a function

The connection ID must be passed as a string with quotes to get_connection().

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that stores secret names and their values from Airflow Variables.

Apache Airflow

secrets = { [1]: Variable.get([2]) for [1] in secret_names }

Drag options to blanks, or click blank then click option'

Aname

B'name'

Csecret

Dsecret_names

💡 Hint

Common Mistakes

Using quotes around the key in the dictionary

Using different variable names in key and get()

The variable name used in the loop and as the key must be the same identifier without quotes.

5fill in blank

hard

Fill all three blanks to filter Airflow Variables whose values are not empty strings.

Apache Airflow

filtered_vars = { [1]: Variable.get([2]) for [1] in Variable.get_all() if Variable.get([3]) != '' }

Drag options to blanks, or click blank then click option'

Akey

B'key'

💡 Hint

Common Mistakes

Using quotes around the variable name in get()

Using different variable names in the comprehension

The loop variable key is used as the dictionary key, and to get the variable value. It must be without quotes.
