because they scoop up all remaining input arguments that are passed to the function. Any formal parameters which occur after the *args parameter are ‘keyword-only’ arguments, meaning that they can only be used as keywords rather than positional arguments.通常，这些变量参数将在正式参数列表中最后...

When calling a function, pass arguments to it, and pass the reference of the actual parameter to the formal parameter according to different parameter types. 1.位置参数:调用函数时实参和形参的顺序必须严格一致,并且实参和形参的数量必须相同。
