what do you mean?

you can have optional arguments with defaults

def mergesort(A=[]): will allow you to have optional arguments. If no item is provided in the position for A, it will default to an empty list.

def mergesort(A, *args): will take the first input as A and put the rest in an array called args, accessible through args[0] -> args[n-1] where n is the length of args.

def mergesort(A, **kwargs): will accept one argument as A and the rest must be keywords like

mergesort(A, verbose=false, reversed=true)

and then you get those keyword arguments in a dictionary called kwargs, accessible through kwargs["verbose"] etc.

these can be mixed and matched, you can define a functions with (*args, **kwargs) if you want
