What Python project management features does Pantsbuild support?

• Python package installations, via Pex & pip
• Isolated envionments for scripts through Pex
• Resolve & lock dependencies, via Poetry and soon Pex
• Builds sdist and wheel packages
• PEP 517 support, see also https://blog.pantsbuild.org/pants-supports-pep-517/
• Experimental support for package publishing
• env variable auto activation for tools and scripts
• Python test automation (using PyTest under the hood)

What features do we implement uniquely?

• Per-project (and per-tool) dependency isolation is usually supported through Hermetic Builds; virtualenvs can be created using ./pants export, but the resulting environments are not directly managed by Pants

What doesn't Pantsbuild provide?

• Python installation management
• Python executable management
• pyproject.toml support
• Non-python package management
