Static type checkers will nowīe able to catch shape-related bugs in code that uses these libraries. In numerical computing libraries such as NumPy and TensorFlow to be In particular, it allows the type of array-like structures This enables a wide variety of use cases. In other words,Ī TypeVarTuple is a variadic type variable, Of generics parameterised with a single type. PEP 484 previously introduced TypeVar, enabling creation This section covers major changes affecting PEP 484 type hints and However, the -64 suffix now implies “not 32-bit” (not necessarily x86-64),Īs there are multiple supported 64-bit platforms.ģ2-bit runtimes are detected by checking the runtime’s tag for a -32 suffix.Īll releases of Python since 3.5 have included this in their 32-bit builds.

Windows py.exe launcher improvements ¶ (Contributed by Irit Katriel in bpo-45607. The added notes appear in the default traceback. That is not available at the time when the exception is raised. It can be used to enrich exceptions with context information The add_note() method is added to BaseException. Irit Katriel, Yury Selivanov and Guido van Rossum.) PEP 678: Exceptions can be enriched with notes ¶ (Contributed by Irit Katriel in bpo-45292. Make it possible to group exceptions and raise them together,Įxcept to match subgroups of exception groups. The builtin types ExceptionGroup and BaseExceptionGroup To raise and handle multiple unrelated exceptions simultaneously.

When printing tracebacks, the interpreter will now point to the exact expression New Features ¶ PEP 657: Fine-grained error locations in tracebacks ¶ Macros converted to static inline functions Py_UNICODE encoder APIs have been removed Many legacy standard library modules have been deprecated and will be removed in Python 3.13 Important deprecations, removals and restrictions: PEP 655: Marking individual TypedDict items as required or not-required Variable to disable automatically prepending potentially unsafe paths to sys.path New -P command line option and PYTHONSAFEPATH environment PEP 657: Fine-grained error locations in tracebacks Support for parsing TOML in the Standard Library PEP 678: Exceptions can be enriched with notes

On average, we measured a 1.25x speedup on the standard benchmark suite. Python 3.11 is between 10-60% faster than Python 3.10.
