Python is rather clever.
Thanks!

To elaborate on Paul's answer, returning the list will also unpack it if
you have it set up that way. E.g.
def func(alist):
return alist
some_list = [1, 2]
this, that = func(alist)
At least, in 2.5.4 this works. :-)
In just about all Python versions for all sequence types, in fact.
Mind you, if you don't have the correct number of return names to match
the unpacking you'll get the normal errors from that.
Yes. This is why people are suggesting that you be consistent about what you
return. This is quite different from Matlab where the interpreter knows how many
return values the caller is expecting in order to overload functions, but I
think it makes for much more understandable code.
