{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"IDLE - Remove use of deprecated sys.last_xyzs in stackviewer","articleBody":"#102778 deprecated sys.last_type/value/traceback in favor of sys.last_exc, added in 3.12.  We cannot access system system-set sys.last_exc in 3.10 and 3.11, but we can set it from sys.last_value or sys.exec_info()[1] and nearly never set or otherwise access the deprecated values.  The except is `sys.last_type, sys.last_value, sys.last_traceback = excinfo` in run.print_exception, which should remain as long as the REPL does the same (add comment).  Any `sys.last_exc = sys.last_value` statements can be deleted in June 2024.  There is a [draft issue](https://github.com/orgs/python/projects/31/views/1?pane=issue\u0026itemId=23303905) for this.\n\nThe files to be patched are run (where it handles exceptions or stackviewer), pyshell (where it starts stackviewer), stackviewer, and test_stackviewer.  [This diff](https://github.com/python/cpython/pull/102825/files) has the relevant locations.\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-103339\n* gh-105526\n* gh-105527\n* gh-105528\n* gh-105534\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/terryjreedy","@type":"Person","name":"terryjreedy"},"datePublished":"2023-03-19T18:00:18.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/102832/cpython/issues/102832"}
