I would expect that strings and bytes keep the trailing zeroes also when added to a `ShareableList`.\r\n\r\n# Your environment\r\n\r\n- CPython versions tested on: 3.8.5, 3.10.6\r\n- Operating system and architecture: Windows 10, 64bit\r\n\r\n# Analysis\r\n\r\nThere are three places in `class ShareableList` in `Lib/multiprocessing/shared_memory.py`, where trailing zeroes are explicitely removed: `...rstrip(b'\\x00')...`. For what reason?\r\n","author":{"url":"https://github.com/coproc","@type":"Person","name":"coproc"},"datePublished":"2022-09-12T21:18:02.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/96779/cpython/issues/96779"}
