When printing tracebacks, the interpreter will now point to the exact expression New Features ¶ Enhanced error locations in tracebacks ¶ The current directory, the script’s directory or an empty string. Variable to not prepend a potentially unsafe path to sys.path such as New -P command line option and PYTHONSAFEPATH environment PEP 655: Marking individual TypedDict items as required or potentially-missing.

Python 3.11 is up to 10-60% faster than Python 3.10.
So it’s worth checking back even after reading earlier versions. It will be updated substantially as Python 3.11 moves towards release, Prerelease users should be aware that this document is currently in draftįorm.
