Are there any uses of the empty tuple in Python?

Question

Is there any other purpose (besides being there because it needs to be) the empty tuple may have? Or: what would you use the empty tuple for? If anything. I just can\'t find

Answer 1

Here's when.

def tuple_of_primes_less_than( n ):
    if n <= 2: return ()
    else:
        x, p = set( range(2,n) ), 2
        while p <= max(x):
            for k in range(2,int(2+math.sqrt(p))):
                x.discard(k*p)
            p += 1
        return tuple( sorted( x ) )
