Previous versions of the interpreter would point to just the line, making itambiguous which object was None. These enhanced errors can also be helpfulwhen dealing with deeply nested dict objects and multiple function calls:
Additionally, the information used by the enhanced traceback featureis made available via a general API, that can be used to correlatebytecode instructions with source code location.This information can be retrieved using:
This feature requires storing column positions in Code Objects,which may result in a small increase in interpreter memory usageand disk usage for compiled Python files.To avoid storing the extra informationand deactivate printing the extra traceback information,use the -X no_debug_ranges command line optionor the PYTHONNODEBUGRANGES environment variable.
PEP 654 introduces language features that enable a programto raise and handle multiple unrelated exceptions simultaneously.The builtin types ExceptionGroup and BaseExceptionGroupmake it possible to group exceptions and raise them together,and the new except* syntax generalizesexcept to match subgroups of exception groups.
The add_note() method is added to BaseException.It can be used to enrich exceptions with context informationthat is not available at the time when the exception is raised.The added notes appear in the default traceback.
The copy of the Python Launcher for Windows included with Python 3.11 has been significantlyupdated. It now supports company/tag syntax as defined in PEP 514 using the-V:/ argument instead of the limited -..This allows launching distributions other than PythonCore,the one hosted on python.org.
PEP 484 previously introduced TypeVar, enabling creationof generics parameterised with a single type. PEP 646 addsTypeVarTuple, enabling parameterisationwith an arbitrary number of types. In other words,a TypeVarTuple is a variadic type variable,enabling variadic generics.
This enables a wide variety of use cases.In particular, it allows the type of array-like structuresin numerical computing libraries such as NumPy and TensorFlow to beparameterised with the array shape. Static type checkers will nowbe able to catch shape-related bugs in code that uses these libraries.
All fields are still required by default,unless the total parameter is set to False,in which case all fields are still not-required by default.For example, the following specifies a TypedDictwith one required and one not-required key:
The new Self annotation provides a simple and intuitiveway to annotate methods that return an instance of their class. Thisbehaves the same as the TypeVar-based approachspecified in PEP 484,but is more concise and easier to follow.
The new LiteralString annotation may be used to indicatethat a function parameter can be of any literal string type. This allowsa function to accept arbitrary literal string types, as well as stringscreated from other literal strings. Type checkers can thenenforce that sensitive functions, such as those that execute SQLstatements or shell commands, are called only with static arguments,providing protection against injection attacks.
PEP 563 Postponed Evaluation of Annotations(the from __future__ import annotations future statement)that was originally planned for release in Python 3.10has been put on hold indefinitely.See this message from the Steering Councilfor more information.
Asynchronous comprehensions are now allowedinside comprehensions in asynchronous functions.Outer comprehensions implicitly become asynchronous in this case.(Contributed by Serhiy Storchaka in bpo-33346.)
A TypeError is now raised instead of an AttributeError inwith statements and contextlib.ExitStack.enter_context()for objects that do not support the context manager protocol,and in async with statements andcontextlib.AsyncExitStack.enter_async_context()for objects not supporting the asynchronous context manager protocol.(Contributed by Serhiy Storchaka in bpo-12022 and bpo-44471.)
Added object.__getstate__(), which provides the defaultimplementation of the __getstate__() method. copyingand pickleing instances of subclasses of builtin typesbytearray, set, frozenset,collections.OrderedDict, collections.deque,weakref.WeakSet, and datetime.tzinfo now copies andpickles instance attributes implemented as slots.This change has an unintended side effect: It trips up a small minorityof existing Python projects not expecting object.__getstate__() toexist. See the later comments on gh-70766 for discussions of whatworkarounds such code may need.(Contributed by Serhiy Storchaka in bpo-26579.)
A "z" option was added to the Format Specification Mini-Language thatcoerces negative to positive zero after rounding to the format precision.See PEP 682 for more details.(Contributed by John Belmonte in gh-90153.)
Bytes are no longer accepted on sys.path. Support broke sometimebetween Python 3.2 and 3.6, with no one noticing until after Python 3.10.0was released. In addition, bringing back support would be problematic due tointeractions between -b and sys.path_importer_cache whenthere is a mixture of str and bytes keys.(Contributed by Thomas Grainger in gh-91181.)
siphash13 is added as a new internal hashing algorithm.It has similar security properties as siphash24,but it is slightly faster for long inputs.str, bytes, and some other typesnow use it as the default algorithm for hash().PEP 552 hash-based .pyc filesnow use siphash13 too.(Contributed by Inada Naoki in bpo-29410.)
When an active exception is re-raised by a raise statement with no parameters,the traceback attached to this exception is now always sys.exc_info()[1].__traceback__.This means that changes made to the traceback in the current except clause arereflected in the re-raised exception.(Contributed by Irit Katriel in bpo-45711.)
A new command line option, AppendPath,has been added for the Windows installer.It behaves similarly to PrependPath,but appends the install and scripts directories instead of prepending them.(Contributed by Bastian Neuburger in bpo-44934.)
The PyConfig.module_search_paths_set field must now be set to 1 forinitialization to use PyConfig.module_search_paths to initializesys.path. Otherwise, initialization will recalculate the path and replaceany values added to module_search_paths.
The output of the --help option now fits in 50 lines/80 columns.Information about Python environment variablesand -X options is now available using the respective--help-env and --help-xoptions flags,and with the new --help-all.(Contributed by ric Araujo in bpo-46142.)
Converting between int and str in bases other than 2(binary), 4, 8 (octal), 16 (hexadecimal), or 32 such as base 10 (decimal)now raises a ValueError if the number of digits in string form isabove a limit to avoid potential denial of service attacks due to thealgorithmic complexity. This is a mitigation for CVE-2020-10735.This limit can be configured or disabled by environment variable, commandline flag, or sys APIs. See the integer string conversionlength limitation documentation. The default limitis 4300 digits in string form.
Added the TaskGroup class,an asynchronous context managerholding a group of tasks that will wait for all of them upon exit.For new code this is recommended over usingcreate_task() and gather() directly.(Contributed by Yury Selivanov and others in gh-90908.)
Added timeout(), an asynchronous context manager forsetting a timeout on asynchronous operations. For new code this isrecommended over using wait_for() directly.(Contributed by Andrew Svetlov in gh-90927.)
The internal _sha3 module with SHA3 and SHAKE algorithms now usestiny_sha3 instead of the Keccak Code Package to reduce code and binarysize. The hashlib module prefers optimized SHA3 and SHAKEimplementations from OpenSSL. The change affects only installations withoutOpenSSL support.(Contributed by Christian Heimes in bpo-47098.)
Change the frame-related functions in the inspect module to return newFrameInfo and Traceback class instances(backwards compatible with the previous named tuple-like interfaces)that includes the extended PEP 657 position information (endline number, column and end column). The affected functions are:
Added a createSocket() methodto SysLogHandler, to matchSocketHandler.createSocket().It is called automatically during handler initializationand when emitting an event, if there is no active socket.(Contributed by Kirill Pinchuk in gh-88457.)
Collation name create_collation() can nowcontain any Unicode character. Collation names with invalid charactersnow raise UnicodeEncodeError instead of sqlite3.ProgrammingError.(Contributed by Erlend E. Aasland in bpo-44688.)
sqlite3 exceptions now include the SQLite extended error code assqlite_errorcode and the SQLite error name assqlite_errorname.(Contributed by Aviv Palivoda, Daniel Shahaf, and Erlend E. Aasland inbpo-16379 and bpo-24139.)
sqlite3 C callbacks now use unraisable exceptions if callbacktracebacks are enabled. Users can now register anunraisable hook handler to improve their debugexperience.(Contributed by Erlend E. Aasland in bpo-45828.)
sys.exc_info() now derives the type and traceback fieldsfrom the value (the exception instance), so when an exception ismodified while it is being handled, the changes are reflected inthe results of subsequent calls to exc_info().(Contributed by Irit Katriel in bpo-45711.)
Three new installation schemes(posix_venv, nt_venv and venv) were added and are used when Pythoncreates new virtual environments or when it is running from a virtualenvironment.The first two schemes (posix_venv and nt_venv) are OS-specificfor non-Windows and Windows, the venv is essentially an alias to one ofthem according to the OS Python runs on.This is useful for downstream distributors who modifysysconfig.get_preferred_scheme().Third party code that creates new virtual environments should use the newvenv installation scheme to determine the paths, as does venv.(Contributed by Miro Hrončok in bpo-45413.)
