[RELEASE] Python 3.14.0 alpha 1 is now available
It's now time for a new alpha of a new version of Python! https://www.python.org/downloads/release/python-3140a1/ **This is an early developer preview of Python 3.14** # Major new features of the 3.14 series, compared to 3.13 Python 3.14 is still in development. This release, 3.14.0a1 is the first of seven planned alpha releases. Alpha releases are intended to make it easier to test the current state of new features and bug fixes and to test the release process. During the alpha phase, features may be added up until the start of the beta phase (2025-05-06) and, if necessary, may be modified or deleted up until the release candidate phase (2025-07-22). Please keep in mind that this is a preview release and its use is **not** recommended for production environments. Many new features for Python 3.14 are still being planned and written. Among the new major new features and changes so far: * PEP 649 (https://peps.python.org/pep-0649/): deferred evaluation of annotations ( https://docs.python.org/3.14/whatsnew/3.14.html#pep-649-deferred-evaluation-of-annotations ) * Improved error messages ( https://docs.python.org/3.14/whatsnew/3.14.html#improved-error-messages) * (Hey, **fellow core developer,** if a feature you find important is missing from this list, [let Hugo know (h...@python.org).) The next pre-release of Python 3.14 will be 3.14.0a2, currently scheduled for 2024-11-19. # More resources * Online documentation: https://docs.python.org/3.14/ * PEP 745, 3.14 Release Schedule: https://peps.python.org/pep-0719/ * Report bugs at https://github.com/python/cpython/issues * Help fund Python and its community: https://www.python.org/psf/donations/ # And now for something completely different π (or pi) is a mathematical constant, approximately 3.14, for the ratio of a circle's circumference to its diameter. It is an irrational number, which means it cannot be written as a simple fraction of two integers. When written as a decimal, its digits go on forever without ever repeating a pattern. Here's 76 digits of π: 3.141592653589793238462643383279502884197169399375105820974944592307816406286 Piphilology is the creation of mnemonics to help remember digits of π. In a pi-poem, or "piem", the number of letters in a word equal the corresponding digit. This covers 9 digits, 3.14159265: > *How I wish I could recollect pi easily today!* One of the most well-known covers 15 digits, 3.14159265358979: > *How I want a drink, alcoholic of course, after the heavy chapters involving quantum mechanics!* Here's a 35-word piem in the shape of a circle, 3.1415926535897932384626433832795728: It's a fact A ratio immutable Of circle round and width, Produces geometry's deepest conundrum. For as the numerals stay random, No repeat lets out its presence, Yet it forever stretches forth. Nothing to eternity. The Guiness World Record for memorising the most digits is held by Rajveer Meena, who recited 70,000 digits blindfold in 2015. The unofficial record is held by Akira Haraguchi who recited 100,000 digits in 2006. # Enjoy the new release Thanks to all of the many volunteers who help make Python Development and these releases possible! Please consider supporting our efforts by volunteering yourself or through organization contributions to the Python Software Foundation.

Code with lots of globals is problematic. Even before your code gets big, discipline helps maintenance. :-) Every level of your program has globals. An application with too many classes is no better (or worse) than a class with too many methods, or a module with too many functions. Insert your own definitions of (and tolerances for) "too many," which will vary in flexibility. I think the need of classes comes when you need objects thus a set of variables with an identity and that may be created N times. Classes are object factories. A second aspect is inheritance: classes may inherit from other classes and reuse existing functionality and data structures for their objects. In cases where you only need to encapsulate a single set of data and functions modules are the best choice. -- https://mail.python.org/mailman/listinfo/python-list
