Mark Dickinson <dickinsm at gmail.com> added the comment:
max and min for a range object are already O(1) one-liners:
>>> a = range(3, 21, 5)
>>> a[-1] if a.step > 0 else a[0] # max(a)
18
>>> a[0] if a.step > 0 else a[-1] # min(a)
3
As for __and__, it doesn't feel like a particularly natural operation to me, given that a range object represents an *ordered* sequence of integers rather than just a subset. For example, what should the first element of
range(7, -3, -2) & range(10)
be? 7 or 1? And why?
