[docs] [issue26582] asyncio documentation links to wrong CancelledError

Andrew Svetlov <andrew.svetlov@gmail.com> added the comment: Moreover, the issue is outdated. asyncio.CancelledError is not an alias of concurrent.futures.CancelledError starting from Python 3.8 Unfortunately, we should make this not 100% backward compatible change. ---------- nosy: +asvetlov _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue26582> _______________________________________
