call f(a, *b) with f(*a, **b) ?

[bukzor]

This question seems easy but I can't figure it out.
Lets say there's a function:

def f(a, *args):
    print a
    for b in args: print b

and elsewhere in your program you have a list and a dict like this:
args = [2, 3]
kwargs = {'a':1}

I'd like to get f() to print something like the following, but I can't
figure out how.
