On behalf of the Python development community and the Python 3.10 release team, I’m pleased to announce the availability of Python 3.10.0. Python 3.10.0 is the newest major release of the Python programming language, and it contains many new features and optimizations.
# Major new features of the 3.10 series, compared to 3.9
Among the new major new features and changes so far:
prepare for the removal of the wstr member in PyUnicodeObject.
union types as X | Y
numbers for debugging and other tools.
Length-Checking To zip.
managers are now officially allowed.

1.1.1 or newer
Py_UNICODE encoder APIs
from __future__ import annotations (PEP 563) used to
be on this list
in previous pre-releases but it has been postponed to Python 3.11 due to
some compatibility concerns. You can read the Steering Council
communication about it here

# And now for something completely different
For a Schwarzschild black hole (a black hole with no rotation or
electromagnetic charge), given a free fall particle starting at the event
horizon, the maximum propper time it will experience to fall into (which
happens when it falls without angular velocity) the singularity is
(in natural units), where M
is the mass of the black hole. For Sagittarius A* (the black hole at the
center of the milky way) this time is approximately 1 minute.
Schwarzschild black holes are also unique because they have a space-like singularity at their core, which means that the singularity doesn't happen at a specific point in *space* but happens at a specific point in *time* (the future). This means once you are inside the event horizon you cannot point with your finger towards the direction the singularity is located because the singularity happens in your future: no matter where you move, you will "fall" into it.
# We hope you enjoy the new releases!
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.
