Python *args **kwargs, passing in an invariant argument to a function, or passing in a lot of content to a function, commonly used in constructors.

" "Example 1: Show the usage of *args, pass in multiple parameters, do not pre-define. In this example, 3 parameters are passed in. There is no pre-defined.

It's basically that much.
