# 2025 Tools & Frameworks Comprehensive Guide

## 🐍 PYTHON ECOSYSTEM (2025)

### Package Management - CRITICAL UPDATE
**Old:** pip, poetry, pipenv
**New:** **uv** - Revolutionary Python package manager

```bash
# Install uv
curl -LsSf https://astral.sh/uv/install.sh | sh

# Usage
uv pip install pydantic structlog
uv sync  # Install from pyproject.toml
uv run python script.py  # Run with virtual env
