[jira] [Created] (BEAM-8538) Python typehints: support namedtuples

Udi Meiri created BEAM-8538:
-------------------------------

             Summary: Python typehints: support namedtuples
                 Key: BEAM-8538
                 URL: https://issues.apache.org/jira/browse/BEAM-8538
             Project: Beam
          Issue Type: Bug
          Components: sdk-py-core
            Reporter: Udi Meiri
            Assignee: Udi Meiri


2 bugs:
1. convert_to_beam_type passes typing.NamedTuple as-is. The code that's supposed to convert it to Any is broken (and the test is buggy too).
Fix: https://github.com/apache/beam/pull/9754/files#diff-9b2eac354738047adddd44814d4b429cR247

2. Possible bug: collections.NamedTuple instances should also be converted to Any, or Tuple[Any, Any, ..], if other static types checker do this as well.
