Q: going from tuple to comma-separated list?

[Damian Menscher]

I've got a function that takes an arbitrary number of parameters.
(This is the Gnuplot.plot() function.)  I don't know until runtime
how many things I want to send to it.  So I thought I'd be clever
and do it as
plotdata = ()
for i in range(stuff):
	plotdata = plotdata + (function(i),)
Gnuplot.plot(plotdata)

But the plot function is dying due to:
TypeError: bad argument type for built-in operation

I realize plotdata is a tuple.  So this is the equivalent of me
calling Gnuplot.plot((0, 1, 2))
Note the double parenthesis...  I'm guessing I just need to get
rid of them.  Is there a way to convert from a tuple to its
non-parenthesized equivalent?

Only thing I can think of would be to do it using a utility function:
def remove_parens(tuple)
	if len(tuple)==1: return tuple[0]
	if len(tuple)==2: return tuple[0], tuple[1]
	if len(tuple)==3: return tuple[0], tuple[1], tuple[2], tuple[3]
...etc.  And I'm not even sure that would work...

Surely there's a better way?

CC's appreciated, but not required.
