**How To Use *args and **kwargs in Python 3**

Introduction In function definitions, parameters are named entities that specify which arguments a function can accept. When you need to support a variable number of arguments without fixing the signature, Python offers two special syntaxes: *args for extra positional arguments and **kwargs for extra keyword arguments. This tutorial covers how to define and call functions with *args and **kwargs, how to combine them with standard and keyword-only parameters, and how to use them in decorators, class inheritance, and type-annotated code. Key Takeaways *args collects extra positional arguments into a tuple; **kwargs collects extra keyword arguments into a dict. Legal argument order in a function signature is: standard positional parameters, then *args, then keyword-only parameters, then **kwargs...
