Cats (library)

Cats is an open-source Python library designed to facilitate the creation of command-line interfaces (CLI). It streamlines building user-friendly, organized, and easily extendable CLI tools by handling argument parsing, command organization, and help documentation automatically. Cats supports features like nested commands, custom input validation, and output formatting, enabling developers to focus on core functionality without worrying about low-level interface details. It is especially useful for developing complex CLI applications, making them more intuitive and maintainable. Essentially, Cats acts as a toolkit that simplifies transforming Python programs into well-structured command-line utilities.
