I'm not sure about the first question, but as for the second, you
could do a few different things. You could just pass the tuple itself
into the function and have the tuple unpacked inside the function.
<code>
f(a)
def f (tuple):
x,y,z = tuple
</code>
You could also pass the elements of the tuple in:
f(a[0], a[1], a[2])
That would do it the way you describe in your post.
