Need to understand Python generator object

In the following:

name = 'TODD'
chars = set('AEIOU')
for ii in range(-1, int(math.copysign(len(name) + 1, -1)), -1):
    if any((cc in chars) for cc in name[ii]):
        print 'Found'
    else:
        print 'Not Found'

I understand that what's inside any(...) is a generator object. What I don't understand is the lack of parentheses - if the parentheses belong to the any() function, shouldn't there be another set of parentheses around the generator expression?

Thanks.
