PYZ

PYZ refers to a file extension commonly associated with Python zip archives. These archives are a way of packaging multiple Python modules, libraries, or even entire applications into a single file for easier distribution and installation. PYZ files are created using Python's built-in zipfile module or external tools.

The primary purpose of a PYZ file is to bundle Python code and associated resources into a single, manageable unit. This can simplify the deployment process, as users only need to handle one file instead of a directory structure. It can also offer a degree of obfuscation, making it more difficult for casual users to inspect the source code directly.

When a Python interpreter encounters a PYZ file, it can often treat it as a regular directory containing Python modules. This allows for seamless importing of modules from within the archive. The exact implementation and support for PYZ files can vary depending on the specific Python version and any packaging tools being used. Some tools might use PYZ files as an intermediate step in creating executable applications.

While not as widely known as other Python packaging formats like wheels or eggs, PYZ files have served a purpose in certain distribution scenarios. Understanding their function helps in comprehending how Python projects can be packaged and shared.
