## Python Environment

- **Python 3.9+**
- **Conda** - Package and environment management
- **pip** - Python package installer


## Dependencies

- Pandas 1.5.0
- NumPy 1.23.0
- Matplotlib 3.6.0
- PyPDF2 3.0.0


## Development Tools

- Black - Code formatting
- isort - Import sorting
- flake8 - Linting

## Python Environment

- **Python 3.11+** - Modern type hints and 10-25% performance improvement
- **UV Package Manager** - Fast, reliable package and environment management (workspace-hub standard)


## Dependencies

- **pandas>=2.0.0** - Data processing with improved performance
- **numpy>=1.24.0** - Numerical computing
- **plotly>=5.14.0** - Interactive visualizations (MANDATORY - workspace-hub standard)
- **pypdf>=3.0.0** - Modern PDF processing (replaces deprecated PyPDF2)

**Note:** All visualizations MUST be interactive (Plotly). No static matplotlib charts per workspace-hub standards.


## Development Tools

- **Ruff** - All-in-one linter, formatter, and import sorter (replaces Black+isort+flake8)
- **mypy** - Static type checking
- **pytest** - Testing framework with coverage reporting
