Prefect Community

Hi community!  which is the best way to map over a dictionary?
and acces the key and value on the mapping function, i could find a example with this!

this is my example code:
```@task
def get_dict():
    new_dict = {0:"hi", 1:"yes", 2:"no"}
    return new_dict

@task
def print_nice_dict(elem):
    print(elem)

with Flow("testing") as f:
    print_nice_dict.map(get_dict)```

and this is my error
```[2020-10-22 21:42:45] ERROR - prefect.FlowRunner | Unexpected error: KeyError(3)
Traceback (most recent call last):
  File "/home/fabian/anaconda3/lib/python3.7/site-packages/prefect/engine/runner.py", line 48, in inner

KeyError: 3
[2020-10-22 21:42:45] ERROR - prefect.testing | Unexpected error occured in FlowRunner: KeyError(3)
&lt;Failed: "Unexpected error: KeyError(3)"&gt;```

```with Flow("testing") as f:
    my_dict = get_dict()
    print_nice_dict.map(my_dict.items())```

that didnt work for me :upside_down_face:

Maybe calling `list(my_dict.items())`? Any indexable iterable should work - but for best results you may want to ensure it is stably sorted.

still getting error, it's seems it doesnt recognize that its a dict object

```AttributeError: 'FunctionTask' object has no attribute items.```

Oh I’m so sorry I didn’t read your setup correctly. Try returning an iterable from your `get_dict()` task - instead of `new_dict` return `list(new_dict().items())`. Then you should be able to map over that directly.

I didn’t realize `my_dict` was the result of a task
mI didn’t realize

no problem! just to know, why a `list` is more stably sorted than a `dict` ?

also try with OrderedDict from collections and didnt worked

`dict` is sorted by convention in Python 3.6+, but you can’t, for example, get the 2nd element by accessing it with `[2]`, it can only be accessed by key.
