Packaging and distribution in Python centers on setuptools, a standard-library-adjacent tool built atop distutils that transforms a source tree into installable artifacts. A "wheel" is a binary distribution containing pre-built code and metadata for direct installation, while an "sdist" (source distribution) is a compressed archive of source files plus the build configuration, enabling rebuilding from source; egg-info is intermediate build metadata largely superseded by the wheel format. This distribution model relies on a central package repository (PyPI) and a companion upload/validation tool (twine) to make packages discoverable and installable via a package manager, forming the standard mechanism by which Python code is shared, versioned, and reused across projects.
