Easy Unpack

Easy Unpack


Your mission here is to create a function that gets a tuple and returns a tuple with only 3 elements - the first, third and second element from the last for the given tuple.

One important thing worth pointing out is that you need to use index in order to extract elements from the tuple. Pay attention, index counting starts from 0, not from 1. Which means that if you need to get the first element from the tuple elements, you should do elements[0], and the second element is elements[1].


Input: A tuple, at least 3 elements long.

Output: A tuple.


assert easy_unpack((1, 2, 3, 4, 5, 6, 7, 9)) == (1, 3, 7)
assert easy_unpack((1, 1, 1, 1)) == (1, 1, 1)
assert easy_unpack((6, 3, 7)) == (6, 7, 3)

(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)

checkio serv -d

Alternatevly, you can install Chrome extension or FF addon

checkio install-plugin --chromium

Read more here about other functionality that the checkio client provides. Feel free to submit an issue in case of any difficulties.
