Python 3.14 is now out! 🐍🥧🎉
My favorite new features include:
• All the color (REPL & PDB syntax highlighting, argparse help, unittest, etc.)
• pathlib's copy & move methods
• date.strptime
• uuid7
• argparse choice typo suggestions
• t-strings
• concurrent subinterpreters
• import tab completion
And that list doesn't even include free-threading, JIT, the external debugger interface, or asyncio introspection!
A 6 minute demo of all my favorite features:

Prefer to read instead of watch a video? I just published an article version of that screencast also (with screenshots to show off the color 🎨): https://pym.dev/python314/

@treyhunner@mastodon.social Looking forward to the lazy evaluation of annotations, too!

@treyhunner@mastodon.social Would that make this Pi-thon?
