-------------------------------------------------------------
In pyarrow 7.0.0 that would be something like this? :
{code:python}
import pyarrow as pa
import pyarrow.compute as pc
low_threshold = 1
high_threshold = 3
arr = pa.array([1, 2, 3])
pc.min_element_wise(pc.max_element_wise(pc.power(arr, 0.5), low_threshold),
high_threshold)
{code}
