The same happens when `stdout` is redirected, but that is to be expected.\r\n\r\nCode (in `test.py`):\r\n```Python\r\nx = input('prompt: ')\r\nprint(x)\r\n```\r\n\r\nWhen run:\r\n``` \r\n\u003e python test.py\r\nprompt: text\r\ntext\r\n\r\n\u003e python test.py \u003eout\r\ntext\r\n\r\n\u003e python test.py 2\u003eerr\r\ntext\r\ntext\r\n```\r\nThe contents of `out` and `err`, respectively:\r\n```\r\n# out\r\nprompt: text\r\n# err\r\nprompt: \r\n```\r\nThe first and second cases are as expected. In the last case, the prompt is not printed, even though it should go into `stdout`, according to the [documentation](https://docs.python.org/3/library/functions.html#input). Instead, it is printed to `err`.\r\n\r\n**Your environment**\r\n\r\n- CPython versions tested on: 3.9.2\r\n- Operating system and architecture: Linux 5.11.0-40-generic #44~20.04.2-Ubuntu SMP Tue Oct 26 18:07:44 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux","author":{"url":"https://github.com/DavidNemeskey","@type":"Person","name":"DavidNemeskey"},"datePublished":"2022-05-12T07:52:33.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/92715/cpython/issues/92715"}
