Hey folks wave I tried mapping over the entries of a `dict`

Question

Hey folks wave I tried mapping over the entries of a `dict` but got the following error ```At least one upstream state has an unmappable result ``` Looking at the docs it seems that `map` should work with an `Iterable` Afaik `dict` is an `Iterable` in Python so I m a bit confused sweat smile I m using Prefect `0 15 16`

What other args you pass in the task

ale · Answer

I am passing two arguments a dict the object on which the mapping should be applied another `unmapped` object

Anna Geller · Answer

Mapping works with lists you could map over a list of dictionaries but not over dictionaries

emre · Answer

I don t think dict is an iterable but `dict items ` is

ale · Answer

Thanks for the suggestions folks much appreciated as usual raised hands pray gratitude thank you

Anna Geller · Answer

I think the easiest would be to map over ```list your dict values ```

Anna Geller · Answer

one task could return the above based on dict as input and pass it to the task doing mapping just one possibility among many

Anna Geller · Answer

< ale> I can confirm it must be a list actually returning just sample dict values would fail but wrapping it with list works ```import prefect from prefect import task Flow task def get iterable sample dict = dict a=1 b=2 c=3 return list sample dict values return sample dict values task def log output x x with Flow map dict test as flow iterable input from dict = get iterable log output map iterable input from dict if name == main flow run ```
