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. WebMar 27, 2024 · String slicing in Python is about obtaining a sub-string from the given string by slicing it respectively from start to end.
