3.9.0 Release highlights New syntax features: PEP 584, union operators added to dict; PEP 585, type hinting generics in standard collections; PEP 614, relaxed grammar restrictions on decorators. New built-in features: PEP 616, string methods to remove prefixes and suffixes. New features in the standard library: PEP 593, flexible function and variable annotations; os.pidfd_open() added that allows process management without races and signals. Interpreter improvements: PEP 573, fast access to module state from methods of C extension types; PEP 617, CPython now uses a new parser based on PEG; a number of Python builtins (range, tuple, set, frozenset, list, dict) are now sped up using PEP 590 vectorcall; garbage collection does not block on resurrected objects; a number of Python modules (_abc, audioop, _bz2, _codecs, _contextvars, _crypt, _functools, _json, _locale, math, operator, resource, time, _weakref) now use multiphase initialization as defined by PEP 489; a number of standard library modules (audioop, ast, grp, _hashlib, pwd, _posixsubprocess, random, select, struct, termios, zlib) are now using the stable ABI defined by PEP 384. New library modules: PEP 615, the IANA Time Zone Database is now present in the standard library in the zoneinfo module; an implementation of a topological sort of a graph is now provided in the new graphlib module.

Python is an interpreted, interactive, object-oriented
|
|
programming language that combines remarkable power with
|
|
very clear syntax. For an introduction to programming in
|
|
Python you are referred to the Python Tutorial. The
|
|
Python Library Reference documents built-in and standard
|
|
types, constants, functions and modules. Finally, the
|
|
Python Reference Manual describes the syntax and semantics
|
|
of the core language in (perhaps too) much detail.
|
|
|
|
Python's basic power can be extended with your own modules
|
|
written in C or C++. On most systems such modules may be
|
|
dynamically loaded. Python is also adaptable as an exten-
|
|
sion language for existing applications. See the internal
|
|
documentation for hints.

This package provides Python version 3.8.x.
