[Python][Docs] Document file path support for IPC reader source

Open krupakargurije opened this issue 2 weeks ago • 1 comments

What changed

Document that IPC reader APIs accept a file path for the source parameter, consistent with existing writer documentation.

Affected APIs

pyarrow.ipc.open_file
pyarrow.ipc.open_stream
pyarrow.ipc.RecordBatchFileReader
pyarrow.ipc.RecordBatchStreamReader

Why

These APIs already accept file paths, but this behavior was undocumented. This PR aligns the reader documentation with actual behavior and with the corresponding writer APIs.

Fixes #46927
