What are PYO files and how to open them

Are you having problems opening a PYO file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your PYO files.

What is a PYO file?

A .PYO file is a Python Optimized Code file.

Python Optimized Code Files, commonly referred to as ".PYO" files, are a type of file format used to store pre-compiled code written in the Python programming language. This type of file is generated when Python code is compiled, allowing it to be directly executed by the Python interpreter without needing to be recompiled.

The .PYO format is designed to make Python code run more quickly by reducing the need for interpretation and recompilation. This makes the performance of .PYO files superior to their .PY counterparts.
