is it possible to map over 2 variables that are lists of equal length? For example, i’d like to get this functionality:

@task
def task(x: str, y: int):
    ...


@flow
def flow():
    list_1, list_2 = ['a', 'b'], [1, 2]
    for input_1, input_2 in zip(list_1, list_2):
        task(input_1, input_2)

Would this be done via:

task.map(list_1 , list_2)

Or will prefect only iterate only one of the parameters?

The

.map

operation will behaviour exactly as you are hoping here, so long as those lists are of equal length, The

prefect

unmapped

function (I think it is in the main namespace) can be used to tell prefect not to iterate / zip over something if need be,

task.map(list_1, unmapped(list_2))

if you want

list_2

to be passed in complete form to each call into

task

@Tim Galvin sweet! just tested it out as well. seems to be working.
