### Rationale for this change Fixes #55418. `pa.record_batch()` accepts `list` or `tuple` of arrays, but `RecordBatch.from_arrays` was Cython-typed as `list arrays`, so a tuple raised `TypeError: Argument 'arrays' has incorrect type (expected list, got tuple)`. `Table.from_arrays` already accepts untyped sequences. ### What changes are included in this PR? - Drop the Cython `list` type annotation on `RecordBatch.from_arrays` so tuples (and other sequences) work, matching `Table.from_arrays`. - Document parameters as list or tuple; clarify the `record_batch()` TypeError message. - Add a unit test for `pa.record_batch((array,), names=...)`. ### Are these changes tested? - Added `test_record_batch_from_tuple_of_arrays` in `python/pyarrow/tests/test_table.py`. - Full pyarrow rebuild/tests were not run in this environment (Cython extension); CI should cover it. ### Are there any user-facing changes? Yes: `pa.record_batch(tuple_of_arrays, ...)` and `RecordBatch.from_arrays(tuple_of_arrays, ...)` now work instead of raising TypeError. ### AI assistance Assisted by an AI coding tool for locating the Cython `list` annotation and drafting this PR text. I reviewed the call path against `Table.from_arrays` and confirmed the failure mode matches issue #55418. * GitHub Issue: #55418 -- This is an automated message from the Apache Git Service.
