Two sets are equal if and only if every element of each set is contained in the other (each is a subset of the other). A set is less than another set if and only if the first set is a proper subset of the second set (is a subset, but is not equal). A set is greater than another set if and only if the first set is a proper superset of the second set (is a superset, but is not equal).\n\u003e\n\u003e Instances of [set](https://docs.python.org/3.14/library/stdtypes.html#set) are compared to instances of [frozenset](https://docs.python.org/3.14/library/stdtypes.html#frozenset) based on their members.\n\nbut we should adjust also the generic texts, something like:\n\u003e Objects of different types, unless documented otherwise, never compare equal.\n\nPS: https://discuss.python.org/t/104658/\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-141221\n* gh-142810\n* gh-142811\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/skirpichev","@type":"Person","name":"skirpichev"},"datePublished":"2025-11-08T00:05:30.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/141218/cpython/issues/141218"}
