## Python Environment Management with uv

uv is a high-performance Python package and project manager written in Rust. Here's how to use it effectively:

### Installing Python Versions
```bash
# Install multiple Python versions
uv python install 3.10 3.11 3.12

# Pin a specific Python version for a project
uv python pin 3.11
```

### Virtual Environment Management
```bash
# Create a new virtual environment
uv venv --python 3.12.0

# Activate the virtual environment
source .venv/bin/activate
```

### Package Management
```bash
# Initialize a new project
uv init project_name

# Add a package to your project
uv add package_name

# Run a Python tool directly without installation
uvx tool_name command

# Install a tool globally
uv tool install tool_name
```

### Requirements Management
```bash
# Compile requirements file
uv pip compile requirements.in --universal --output-file requirements.txt

# Install dependencies from requirements file
uv pip sync requirements.txt
```

## Important Notes

1. Environment Activation:
   - Check if virtual environment activation is needed before running commands
   - Use `source .venv/bin/activate` to activate
