pass value to function with * and/or **

[Skaperen]

if i define a function like:

def foo(*boo,**hoo):
    ...
    return (boo,hoo)

then call it while passing a created type that operates like a list or dictionary, will these values in the function (e.g. boo and hoo in the above code) have the types as passed or will they be converted to list or dictionary, as appropriate?
