Python Development

What's New (2025-2026)

Python 3.14 (Oct 2025)

• Template strings (PEP 750): t"Hello {name}" - safe SQL/HTML interpolation
• Incremental GC: 10ms pauses (was 100ms)
• uuid7: Time-ordered UUIDs (better for DBs)
• Remote pdb: python -p PID

Tooling

Tool	Notes
ty	Astral's type checker, 10-60x faster than mypy
Ruff 0.8+	Type-aware linting, 800+ rules
uv 0.5+	Stable, production-ready

uv init myproject && cd myproject              # New project
uv add requests pydantic httpx                 # Add deps
uv add --dev pytest ruff                       # Dev deps
uv  --locked                               
uv run python main.py
