It’s now time for a new alpha of a new version of Python!
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: deferred evaluation of annotations
- PEP 741: Python configuration C API
- Improved error messages
- (Hey, fellow core developer, if a feature you find important is missing from this list, let Hugo know.)
The next pre-release of Python 3.14 will be 3.14.0a2, currently scheduled for 2024-11-19.

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:

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.
