Vlad Firoiu commented on ARROW-15033:
-------------------------------------
Here's what I'm looking for:
{code:python}
reference = pa.array([[1, 2, 3], [4, 5, 6]])
sub_arrays = [
pa.array([1, 4]),
pa.array([2, 5]),
pa.array([3, 6]),
]
list_array = pa.ListArray.from_sub_arrays(sub_arrays)
assert list_array == reference
{code}
> [Python] No way to create ListArray from sub-arrays

> Project: Apache Arrow
> Issue Type: New Feature
> Components: Python
> Reporter: Vlad Firoiu
> Priority: Major
>
> I'd like to create a `ListArray` from a list of sub-arrays, similar to how
> `StructArray.from_arrays` can create a `StructArray` from a sequence of names
> and arrays. A similarly-named function, `ListArray.from_arrays` does exist,
> but it does something completely different.
