Hi 👋 Does anyone know how (if at all possible) to iterate over a

prefect.Paramter

? My question in more detail: https://stackoverflow.com/questions/64155793/is-it-possible-to-loop-over-a-prefect-parameter

Hi @Newskooler - look at mapping Also the input param name needs to be in quotes I.e “url_list”

Hi @itay livni I am not following what you are saying. Which mapping are you referring to? and by “Also the input param name needs to be in quotes  I.e “url_list” are you saying I cannot past a list?

You can absolutely pass a list but your param name is &...&.... it should just be a string On my phone otherwise I’d give you an example A parameter in prefect is a special task So it needs a name

Thanks I will dig in and try and see what you mean. So far I think I managed to achieve this by

.map()

which is quite handy.

And instead of “for_urls” use get_url.map(list)

Hi @Newskooler -

.map

is definitely the way to go, you can use that over any iterable. The difference between what you've described in your SO post is you're trying to use normal looping over the Parameter (which, as @itay livni described is a special task). But using the special

.map

method will give you the results you're expecting and give you better insight into that process to boot.

Thanks @nicholas whoever came up with

.map

and

unmapped

from the Prefect team, deserves a beer! 🍻

They're quite useful huh?! 😄

Yeah; very much so.
