Flask - Background Tasks

Given this code snippet in a Flask app with Celery:

@celery_app.task
def multiply(x, y):
    return x * y

result = multiply.delay(3, 4)
print(result.get())

What will be printed?

AA task object reference

Bnull

C12

DAn error because delay() is not valid

Step-by-Step Solution

Solution:

Step 1: Understand delay() usage
Calling multiply.delay(3, 4) sends the task to Celery to run asynchronously.
Step 2: Using get() to wait for result
result.get() waits for the task to finish and returns the output, which is 3 * 4 = 12.
Final Answer:
12 -> Option C
Quick Check:
delay() runs task, get() returns result [OK]

Quick Trick: delay() runs task, get() fetches result [OK]
