Adam Lippai commented on ARROW-17821:
-------------------------------------
Exactly! The main challenge is that I have two columns with equal length lists,
practically a sorted 1to1 mapping, but I can use this info.
My final goal is solving

> Key: ARROW-17821
> URL: https://issues.apache.org/jira/browse/ARROW-17821
> Project: Apache Arrow
> Issue Type: New Feature
> Components: C++, Python
> Reporter: Adam Lippai
> Priority: Major
>
> If column A has list\(x), column B has list\(y), column C has list(z), I'd
> like to be able to create D = zip(A,B,C) where D would be list(\{ A: x, B: y,
> C: z}).
> x, y, z are types in the example, type of the resulting is D is list(struct).
> Other features to consider:
> * Zipping list(struct) with list\(x) or list(struct) with list(struct)
> should be able to merge
> * Zipping A,B into a Map with keys from A, values from B
