PrettyPrinter

PrettyPrinter is a Python library (version 0.18.0) that offers syntax-highlighting, declarative, and composable pretty printing for Python 3.5+ data structures. It aims to be a feature-rich alternative to Python's standard `pprint` module, providing improved readability, customizability, and integrations with other libraries. Its release cadence has been somewhat irregular, but the 0.18.0 version released in 2019 has been stable, suggesting a mature library.
