swap_ends

Given a list of ints, swap the first and last elements in the list. Return the modified list. The list length will be at least 1.

swap_ends([1, 2, 3, 4]) -> [4, 2, 3, 1]
swap_ends([1, 2, 3]) -> [3, 2, 1]
swap_ends([8, 6, 7, 9, 5]) -> [5, 6, 7, 9, 8]

This exercise was taken from codingbat.com and has been adapted for the Python language. There are many great programming exercises there, but the majority are created for Java.

Starter Code

from typing import List


def swap_ends(nums: List[int]) -> List[int]:
    pass


result = swap_ends([1, 2, 3, 4])
print(result)

Tests

from main import swap_ends


def test_swap_ends_1():
    assert swap_ends([1, 2, 3, 4]) == [4, 2, 3, 1]


def test_swap_ends_2():
    assert swap_ends([1, 2, 3]) == [3, 2, 1]


def test_swap_ends_3():
    assert swap_ends([8, 6, 7, 9, 5]) == [5, 6, 7, 9, 8]


def test_swap_ends_4():
    assert swap_ends([3, 1, 4, 1, 5, 9]) == [9, 1, 4, 1, 5, 3]


def test_swap_ends_5():
    assert swap_ends([1, 2]) == [2, 1]


def test_swap_ends_6():
    assert swap_ends([1]) == [1]
