It's at the discretion of the package maintainer, but it's pretty common. Just look at the `Formula.rb` for any standalone app in Python or Lua. Example: https:

Example: https://github.com/Homebrew/homebrew-core/blob/66c42fbd814b3a0c291fb872a569abc441747685/Formula/l/locust.rb#L26-L129 https://github.com/Homebrew/homebrew-core/blob/66c42fbd814b3... I think using per-project venv is still the sensible thing to do, not just in Python but using the equivalent in Lua (hererocks), Ruby (Bundler), etc. This is for system-wide installations of standalone CLI tools and other "apps". However if you do find something on PyPI that is a standalone app, but isn't in Homebrew, you can create an isolated env for it automatically using Pipx https://pypa.github.io/pipx/ https://pypa.github.io/pipx/.
