A wheel is a zip-style archive that contains all the files necessary for a typical package installation.
Python packages installed with pip on Windows are typically bundled into ‘wheels’ prior to installation. For more information on how to use pip, see the Pip Package Installation instructions below. By default, pip installs packages located in the Python Package Index (PyPI), but can also install from other indexes. The pip command has options for installing, upgrading and deleting packages, and can be run from the Windows command line. Pip is installed automatically with Python 2 (>=2.7.9) and Python 3 (>=3.4) installations. The Pip Package Manager is the de facto standard for managing Python distributions, and is recommended for installing Python packages for Windows.
