package

syntax

• Python packages name should also have short, all-lowercase names. The use of underscores is discouraged
  • It should match the Regex ^([A-Z0-9]|[A-Z0-9][A-Z0-9._-]*[A-Z0-9])$
• Python packages can only be published as a bundle, the Project level. Project always include multiple packages.
• Python project doesn't have strict naming convention
• Python package downstream user can import Package, but not Project
• Python package extra only enclose dependencies, not source code.
  • Thus it cannot provide source code isolation
  • To wrap source code together with dependencies, you need to make it in an isolated pyproject.

pypi

• No unpublish: PyPI does not allow for a filename to be reused, even once a project has been deleted and recreated.
• pip package installation is case-insensitive and treats underscores and hyphens equivalently.
• No download statistics
  • Alternatively: project linehaul feed the PyPI public BigQuery dataset via Google Cloud Functions.
