AlenkaF opened a new issue, #40273:
URL: https://github.com/apache/arrow/issues/40273
### Describe the enhancement requested
We want to enable the construction of a Run-End Encoded arrays with
`pyarrow.array` constructor. Example:
```python
>>> arr = [1, 2, 2, 3, 3, 3]
>>> ree_arr = pc.run_end_encode(arr)
>>> ree_type = pa.run_end_encoded(pa.int32(), pa.int64())
>>> pa.array(ree_arr) # Works
<pyarrow.lib.RunEndEncodedArray object at 0x12ef46620>
-- run_ends:
[
1,
3,
6
]
-- values:
[
1,
2,
3
]
>>> pa.array(arr, type=ree_type) # Fails
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "pyarrow/array.pxi", line 343, in pyarrow.lib.array
result = _sequence_to_array(obj, mask, size, type, pool, c_from_pandas)

return check_status(status)
File "pyarrow/error.pxi", line 91, in pyarrow.lib.check_status
raise convert_status(status)

```
