Python Learn the basics Quiz 56

Q>

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

(여기서 당신의 임무는 튜플을 얻고 주어진 배열의 첫 번째, 세 번째, 두 번째의 세 요소를 가진 튜플을 반환하는 함수를 만드는 것입니다.)

 

Input: A tuple, at least 3 elements long.

        (최소한 3 요소 길이의 튜플.)

 

Output: A tuple.

           (튜플.)

 

Example:

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

def easy_unpack(elements: tuple) -> tuple:
    """
        returns a tuple with 3 elements - first, third and second to the last
    """
    # your code here
    return elements[0], elements[2], elements[-2]

if __name__ == '__main__':
    print('Examples:')
    print(easy_unpack((1, 2, 3, 4, 5, 6, 7, 9)))

    # These "asserts" using only for self-checking and not necessary for auto-testing
    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)
    print('Done! Go Check!')

Examples:
(1, 3, 7)
Done! Go Check!
