WebTo make an empirical claim about time complexity, you'd have to time it for various sized lists over different magnitudes, since O (n) refers to how the time taken will change in relation to the input. In this case, reversed isn't doing any iteration, it is lazy. It won't take any time until you actually iterate over it. WebThe time complexity of the sum () function is linear in the number of elements in the iterable ( list, tuple, set, etc.). The reason is that you need to go over all elements in the iterable and add them to a sum variable. Thus, you need to “touch” every iterable element once. Python sum () Dictionary Values
