- Update to 3.13.0:
Major new features of the 3.13 series, compared to 3.12
Some of the new major new features and changes in Python 3.13 are:
- New features
- A new and improved interactive interpreter, based on
PyPy's, featuring multi-line editing and color support, as
well as colorized exception tracebacks.
- An experimental free-threaded build mode, which disables
the Global Interpreter Lock, allowing threads to run
more concurrently. The build mode is available as an
experimental feature in the Windows and macOS installers as
well.
- A preliminary, experimental JIT, providing the ground work
for significant performance improvements.
- The locals() builtin function (and its C equivalent)
now has well-defined semantics when mutating the
returned mapping, which allows debuggers to operate more
consistently.
- A modified version of mimalloc is now included, optional
but enabled by default if supported by the platform, and
required for the free-threaded build mode.
- Docstrings now have their leading indentation stripped,
reducing memory use and the size of .pyc files. (Most tools
handling docstrings already strip leading indentation.)
- The dbm module has a new dbm.sqlite3 backend that is used
by default when creating new files.
- WASI is now a Tier 2 supported platform. Emscripten is
no longer an officially supported platform (but Pyodide
continues to support Emscripten).
- Typing
- Support for type defaults in type parameters.
- A new type narrowing annotation, typing.TypeIs.
- A new annotation for read-only items in TypeDicts.
- A new annotation for marking deprecations in the type
system.
- Removals and new deprecations
- PEP 594 (Removing dead batteries from the standard library)
scheduled removals of many deprecated modules: aifc,
audioop, chunk, cgi, cgitb, crypt, imghdr, mailcap, msilib,
nis, nntplib, ossaudiodev, pipes, sndhdr, spwd, sunau,
telnetlib, uu, xdrlib, lib2to3.
- Many other removals of deprecated classes, functions and
methods in various standard library modules.
- C API removals and deprecations. (Some removals present
in alpha 1 were reverted in alpha 2, as the removals were
deemed too disruptive at this time.)
- New deprecations, most of which are scheduled for removal
from Python 3.15 or 3.16.
- For more details on the changes to Python 3.13, see What's
new in Python 3.13 in the documentation.

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.
