Wheel
Wheel is a built-in Python package format designed for binary distribution of Python packages, particularly those with C extensions or compiled components. It provides a standardized way to package and install Python software, replacing the older .egg format. Wheels are faster to install than source distributions because they don't require compilation during installation.
Developers should use Wheel when distributing Python packages that need to be installed efficiently, especially for packages with native code dependencies. It's essential for creating platform-specific distributions (like for Windows, macOS, or Linux) and for ensuring consistent installations across different environments. Wheel is the recommended format for Python package distribution on PyPI.
