Activate Python virtual environment automatically on iTerm2

1. Create a function in the .zshrc

# ~/.zshrc
activate() {
  if [ -d ".venv" ]; then
    source .venv/bin/activate
  else
    : # ignore if no .venv
  fi
}

2. Set iTerm to call this function on a new tap

iTerm2: Preferences -> Profiles -> Command: Login Shell -> Send text at start: "activate"
