(Not the Python repl which will exit due to some run time error, the terminal itself is messed up)\n\n### CPython versions tested on:\n\nCPython main branch\n\n### Operating systems tested on:\n\nLinux\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-138617\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/gaogaotiantian","@type":"Person","name":"gaogaotiantian"},"datePublished":"2025-02-16T02:02:16.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":8},"url":"https://github.com/130168/cpython/issues/130168"}
