[Python] Polars selectors for columns that are Nested Types

Some Polars operations, such as .sort() fail when passed a column with a Nested Type.

This (sensible) choice about sort means I cannot use my usual sorting pattern of df.sort(pl.all()).

import polars as pl

NESTED_TYPES = [
pl.List,
pl.Array,
pl.Object,
pl.Struct
]
pl.exclude(NESTED_TYPES)


Result:

*.exclude([Dtype(List(Null)), Dtype(Array(Null, 0)), Dtype(Object("object", None)), Dtype(Struct([]))])


Is there a way to select (or exclude) only nested types?

The Selectors Documentation has many ideas but nothing seems right for this.
