Hi everyone Given ```node pre process inputs = dataset param

Question

Hi everyone Given ```node pre process inputs = dataset params pre process outputs = pre processed dataset ``` Kedro will pass ` params pre process ` as a dict to `pre process` which results in a bit of an opaque function s signature `def pre process df pd DataFrame params dict ` Is there a kedro way of unpacking this dict and therefore have more transparent signature with individual params specified Thx M

If your function take multiple arguments why not pass specific parameters instead of the whole dict `params pre process key1` `params pre process key2`

I guess I was feeling lazy sweat smile

Marc Gris · Answer

The function actually has per clean code standards too many params 7 and I wanted the node definition itself to be as uncluttered as possible More serioulsy If the function signature change with unpacking I only need to modify the params file While with explicit hardcoded argument passing I ll also need to refactor the node definition

Nok Lam Chan · Answer

I guess what you are looking for is something like ` params pre process` this is not a valid syntax

Marc Gris · Answer

Exactly I even felt lucky and gave it a shot just in case wink Is the fact that it is non valid syntax an opinionated decision Or is it simply because it hasn t been implemented yet

Nok Lam Chan · Answer

I don t have the context when this is implemented My gut feeling is the former I guess this is not too hard to create a helper in your node function ```def node func params target func params ``` Did I miss a clear solution for this Cc < Juan Luis> < datajoely>

Goal for this is making it easier to map Python func gt Node when possible while not breaking anything

The other related version of this you can t override ` kwargs` in modular pipelines
