This is not a bug. No copy is made at all, neither shallow nor deep. This is described in the documentation for built-in types: https://docs.python.org/3/library/stdtypes.html#common-sequence-operations and is similar to the issue in the FAQs: https://docs.python.org/3/faq/programming.html#id16 I acknowledge that this is sometimes confusing for beginners, but it is just one of those things that programmers have to learn. Sequence multiplication does not copy the items, it replicates references to the same item. ---------- nosy: +steven.daprano resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45169> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
