Python 2.7 reached end-of-life

What this means for you
No more bug fixes, security patches, or improvements to Python 2 from the core team. Anything still on 2.7 runs unmaintained; new CVEs will not be fixed upstream.
Where to go
Move to Python 3. The 2to3 tool and the compatibility notes in the porting guide cover most mechanical changes; the harder work is usually str/bytes handling and dependencies that dropped 2.x support.
- Python 3.x (the supported line)
The Python core team set 1 January 2020 as the hard stop after more than a decade of warnings and one extension. It is the canonical example of a well-run sunset: a fixed date, announced far in advance, held firm — which is exactly why so much tooling finally moved.
