six 1.17.0: six.int2byte raises struct.error rather than ValueError on out-of-range integers, six.remove_move raises AttributeError instead of KeyError on missing moves, and six exception helpers strictly enforce BaseException types

This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. six.int2byte raises struct.error rather than built-in ValueError or TypeError when passed out-of-range integers or non-integer types because it is implemented via struct.Struct.pack in Python 3
  2. six.byte2int raises IndexError on empty byte strings and TypeError on non-subscriptable types via operator.itemgetter
  3. six.indexbytes raises IndexError on out-of-bounds indices and TypeError on non-subscriptables
  4. six.raise_from raises TypeError when cause or target does not derive from BaseException, while setting __cause__ to None and __suppress_context__ to True when cause is None
  5. six.reraise raises TypeError when given an invalid traceback object or when instantiating an uncallable type
  6. six.remove_move raises AttributeError rather than KeyError when attempting to delete an unregistered move
  7. six.ensure_binary, six.ensure_text, and six.ensure_str raise TypeError with exact message formatting when passed unsupported object types
