Python slicing time complexity
WebOct 19, 2024 · What is the time complexity of list slicing in Python? 3 Answers. Getting a slice is O( i_2 – i_1 ). This is because Python’s internal representation of a list is an array, so you can start at i_1 and iterate to i_2 . You can also look at the implementation in the CPython source if you want to. What is the time complexity of list slicing? 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.
