Software Packaging & Distribution
distutils — Building and installing Python modules
package provides support for building and installing additional modules into a Python installation. The new modules may be either 100%-pure Python, or may be extension modules written in C, or may be collections of Python packages which include modules coded in both Python and C.
ensurepip — Bootstrapping the pip installer
package provides support for bootstrapping the
pip installer into an existing Python installation or virtual environment. This bootstrapping approach reflects the fact that
pip is an independent project with its own release cycle, and the latest available stable version is bundled with maintenance and feature releases of the CPython reference interpreter.
venv — Creation of virtual environments
zipapp — Manage executable Python zip archives
