Hi all 👋 I'm a little confused regarding using regular functions (not tasks) in flows and cannot find information about this in the docs. Maybe I did not look in the write place ? For instance, in

with Flow("my-flow") as f:
    a = make_a()
    b = make_b()
    c  = a + b

• Do

make_a

and

make_b

need to be tasks or can they be regular functions ? • In particular, when using builtin functions (for instance,

datetime.utcnow()

), can we use it directly or must we wrap it in a task ? • Is

c = a + b

allowed ? Thanks a lot !

1. make_a and make_b must be tasks in the current Prefect. In Orion, you will be able to call any Python code in your flow, but this is not the case in Prefect <= 1.0 2. You should wrap it in a task 3. Yes, you can see this best when you do

flow.visualize()

- this will give you a DAG visualization

Thanks Anna!
