Keynote 1: What's New in Python
summary
Survey of concrete changes: live REPL demos of syntax (walrus, positional‑only params, f‑strings with =), typing becoming simpler (use list, dict, | as Union), new stdlib modules (ZoneInfo, tomllib), and structural pattern matching examples with case/match. Claims include measured speedups—3.11: 10–60% faster—and clearer tracebacks (PEP 657). Code samples run in the interpreter or error under older versions; PEP numbers and exact examples are cited for followup.
