python-3.13.5-macos11.pkg
Many Python programmers report substantial productivity gains and feel the language encourages the development of higher quality, more maintainable code.
Python runs on macOS, Windows, Linux/Unix, OS/2, Amiga, Palm Handhelds, and Nokia mobile phones. The tool has also been ported to the Java and .NET virtual machines.
The app is distributed under an OSI-approved open source license that makes it free to use, even for commercial products.
Some of its key distinguishing features include:
- Very clear, readable syntax
- Strong introspection capabilities
- Intuitive object orientation
- Natural expression of procedural code
- Full modularity, supporting hierarchical packages
- Exception-based error handling
- Very high level dynamic data types
- Extensive standard libraries and third party modules for virtually every task
- Extensions and modules easily written in C, C++ (or Java for Jython, or .NET languages for IronPython)
- Embeddable within applications as a scripting interface

What's new in this version:
Windows:
- Avoid distributing modified pyconfig.h in the traditional installer. Extension module builds must always specify Py_GIL_DISABLED when targeting the free-threaded runtime.
Tests:
- Add test.support.subTests()
Library:
- Do not normalize locale name ‘C.UTF-8’ to ‘en_US.UTF-8’
- Restore support of integer-like objects with __index__() in random.getrandbits()
- Raise a correct exception for values greater than 0x7fffffff for the BINSTRING opcode in the C implementation of pickle
- Backported bugfixes in zipfile.Path from zipp 3.23. Fixed .name, .stem and other basename-based properties on Windows when working with a zipfile on disk
- email: Fix TypeError in email.utils.decode_params() when sorting RFC 2231 continuations that contain an unnumbered section
- email: Fix parsing of email message ID with invalid domain
- Fix libc thread safety issues with os by replacing getlogin with getlogin_r re-entrant version
- Fix formatting issues in json.dump() when both indent and skipkeys are used
Core and Builtins:
- Roll back changes to generator and list comprehensions that went into 3.13.4 to fix gh-127682, but which involved semantic and bytecode changes not appropriate for a bugfix release
C API:
- Fix Py_RETURN_NONE, Py_RETURN_TRUE and Py_RETURN_FALSE macros in the limited C API 3.11 and older: don’t treat Py_None, Py_True and Py_False as immortal
- Implement PyObject_DelAttr() and PyObject_DelAttrString() as macros in the limited C API 3.12 and older
