Consider the following options instead:\r\n\r\n  - reading the Python tutorial: https://docs.python.org/3/tutorial/\r\n  - posting in the \"Users\" category on discuss.python.org: https://discuss.python.org/c/users/7\r\n  - emailing the Python-list mailing list: https://mail.python.org/mailman/listinfo/python-list\r\n  - searching our issue tracker (https://github.com/python/cpython/issues) to see if\r\n    your problem has already been reported\r\n--\u003e\r\n\r\n# Bug report\r\n\r\nIf you have a directory called `index.html` or `index.htm` within a directory (any name in `SimpleHTTPRequestHandler.index_pages`), it causes http.server to return a 404 Not Found error instead of the directory listing. This comes about due to not checking that the index is a regular file when it checks for its presence. The 404 error comes from the call to open() the directory raising an OSError.\r\n\r\nTo reproduce create a folder structure like below and run python3 -m http.server -d foo. You will get a 404 error rather than a directory listing.\r\n```\r\nfoo/\r\nfoo/\r\n├── bar\r\n└── index.html/\r\n    └── baz\r\n```\r\n\r\n# Your environment\r\n\r\n\u003c!-- Include as many relevant details as possible about the environment you experienced the bug in --\u003e\r\n\r\n- CPython versions tested on: 3.11.0, Python 3.12.0a3 (c3c7848a)\r\n- Operating system and architecture: Fedora Linux 37 (Workstation Edition) x86_64\r\n\u003c!--\r\nYou can freely edit this text.
