python -m venv .venv                           # Create virtual environment
source .venv/bin/activate                      # Activate (macOS/Linux)

Why Use .venv Instead of venv

  • Dot prefix makes the folder hidden in Unix-like systems
  • Keeps vaults clean and avoids accidental sync/edit
  • Recognized by VS Code and Python tooling
  • Easy to exclude via .gitignore
