@Marvin Can I nest a task within a task?

In Prefect 3.x, you cannot directly nest a task within another task. Tasks are designed to be independent units of work. However, you can achieve a similar effect by orchestrating task execution through a flow, which can call multiple tasks in sequence or parallel. Here's a basic structure using Prefect's imperative style:

python
from prefect import flow, task

@task
def inner_task(x):
    return x * 2

@task
def outer_task(y):
    result = inner_task(y)
    return result

@flow
def my_flow(z):
    result = outer_task(z)
    print(result)

my_flow(10)

In this example,

inner_task

is called within

outer_task

, but both are defined as separate tasks. The flow

my_flow

orchestrates the execution. This approach maintains task independence while allowing for nested-like behavior. For more details on writing tasks in Prefect, you can refer to the Prefect 3.x documentation on writing tasks.
