Actually in most cases you don't need to assume it's a list; any iterable is usually good enough. You can always turn it into a list (or a tuple or a set or..) in the function if you really have to. So when you do have to and when you don't ? You don't have to if all you do is iterate over the elements. This is true even if you want to iterate more than once; just use the itertools.tee() function to create N independent iterators. To sum up, a better signature for your function is likely to be "def fn(iterable, cmp=cmp)". George -- http://mail.python.org/mailman/listinfo/python-list
