hombit opened a new issue, #39129:
URL: https://github.com/apache/arrow/issues/39129
### Describe the bug, including details regarding any error messages,
version, and platform.
`pyarrow` doesn't support byte-swapped arrays, but it doesn't check it for
list-arrays. So this code would fail with an assertion error, because the
scalar equals 256 instead of 1:
```python
import numpy as np
import pyarrow as pa
# Big-endian byte order
np_a = np.array([1], dtype='>u2')
# Build a list array, supposed to be [[1]]
pa_a = pa.array([np_a])
scalar = pa_a[0][0]
# The scalar is 256 here, not 1
assert scalar.as_py() == 1, f'{scalar} != 1'
```
I believe that an expected behavior is to fail with
`ArrowNotImplementedError: Byte-swapped arrays not supported`, just like this
code would do:
```python
import numpy as np
import pyarrow as pa
# Big-endian byte order
np_a = np.array([1], dtype='>u2')
pa_a = pa.array(np_a)
```
### Environment
- Linux 4.18.0 x86_64
- Python 3.9.13
- Pyarrow 14.0.1
### Component(s)
Python
