What are wheels?

Wheels are the new standard of Python distribution and are intended to replace eggs. Support is offered in pip >= 1.4 and setuptools >= 0.8.
Advantages of wheels

Faster installation for pure Python and native C extension packages.
Avoids arbitrary code execution for installation. (Avoids setup.py)
Installation of a C extension does not require a compiler on Windows or macOS.
Allows better caching for testing and continuous integration.
Creates .pyc files as part of installation to ensure they match the Python interpreter used.
More consistent installs across platforms and machines
