Tuples as function args

tuples.py

#A function with an optional argument
def foo(fee, far=None, fleeb="floob"):
    print fee
    if far:
        print far

    if fleeb:
        print fleeb

#A function that accepts a tuple as its argument, and then calls another function using the accepted tuple as arguments for the called function
def bar(foo_args):
    foo(*foo_args)

#Obviously tuples can't look like this - how do I set fleeb in the above function?
#bar(("Hi", fleeb="ho"))

#Will I have to do this?
bar(("Hi", None, "Fleeber"))
