args and kwargs in Python 3

Mastering how to use args and kwargs in Python 3 is one of the most powerful and frequently used advanced techniques at Progressive Robot — these special syntaxes allow functions to accept a variable number of positional (*args) and keyword (**kwargs) arguments, making your code more flexible, reusable, generic, and future-proof for everything from utility functions, decorators, API wrappers, logging, data processors, CLI tools, to framework-level code.
