Python 3.14 is the latest stable release of the Python
programming language, with a mix of changes to the language,
the implementation, and the standard library. The biggest
changes include template string literals, deferred evaluation
of annotations, and support for subinterpreters in the standard
library.
The library changes include significantly improved capabilities
for introspection in asyncio, support for Zstandard via a new
compression.zstd module, syntax highlighting in the REPL, as
well as the usual deprecations and removals, and improvements
in user-friendliness and correctness.
- Interpreter improvements:
- PEP 649 and PEP 749: Deferred evaluation of annotations
- PEP 734: Multiple interpreters in the standard library
- PEP 750: Template strings
- PEP 758: Allow except and except* expressions without
brackets
- PEP 765: Control flow in finally blocks
- PEP 768: Safe external debugger interface for CPython
- A new type of interpreter
- Free-threaded mode improvements
- Improved error messages
- Incremental garbage collection
- Significant improvements in the standard library:
- PEP 784: Zstandard support in the standard library
- Asyncio introspection capabilities
- Concurrent safe warnings control
- Syntax highlighting in the default interactive shell, and
color output in several standard library CLIs

Python 3 in SUSE
==============
* Subpackages *
Python 3 is split into several subpackages, based on external dependencies.
The main package 'python3' has soft dependencies on all subpackages needed to
assemble the standard library; however, these might not all be installed by default.
If you attempt to import a module that is currently not installed, an ImportError is thrown,
with instructions to install the missing subpackage. Installing the subpackage might result
in installing libraries that the subpackage requires to function.
* ensurepip *
The 'ensurepip' module from Python 3 standard library (PEP 453) is supposed to deploy
a bundled copy of the pip installer. This makes no sense in a managed distribution like SUSE.
Instead, you need to install package 'python3-pip'. Usually this will be installed automatically
with 'python3'.
Using 'ensurepip' when pip is not installed will result in an ImportError with instructions
to install 'python3-pip'.
* Documentation *
You can find documentation in seprarate packages: python3-doc and
python3-doc-pdf. These contan following documents:
Tutorial, What's New in Python, Global Module Index, Library Reference,
Macintosh Module Reference, Installing Python Modules, Distributing Python
Modules, Language Reference, Extending and Embedding, Python/C API,
Documenting Python
The python3-doc package constains many text files from source tarball.
* Interactive mode *
Interactive mode is by default enhanced with of history and command completion.
If you don't like these features, you can unset the PYTHONSTARTUP variable
in your .profile or disable it system wide in /etc/profile.d/python.sh.
