PyON

Pyon is a term that may refer to several distinct concepts. In computing, it most often denotes PyON, short for Python Object Notation, and the suite of open-source libraries that implement it for Python. In Japanese pop culture, pyon is also a common onomatopoeic sound used in manga and anime to indicate a light hopping or popping motion.

PyON (Python Object Notation) is a data-interchange format designed to be readable by humans and easy to map to Python data structures. A PyON document expresses standard types such as numbers, strings, booleans, None, and the built-in containers like lists and dictionaries, and can also represent nested and composite objects. The accompanying Python libraries provide functions to encode Python objects into PyON text and to decode PyON text back into Python objects, enabling straightforward data exchange and persistence within Python-centric workflows.

In Japanese media, "pyon" is an onomatopoeic word representing a small hop or popping motion. It is frequently used in dialogue, captions, or sound-effect text to convey movement, such as a rabbit leaping or a ball bouncing. The form and usage are common in children's books, manga, and anime, where it helps evoke whimsy or lightness.

Because the same term covers different domains, the precise meaning depends on context, and some uses may refer to specific projects or brands named Pyon.
