Find an even number. Complete the following function according to its docstring. Use a for loop. The lists we test will not all be shown; instead, some will be described in English. If you fail any test cases, you will need to read the description and make your own test. from typing import List def first_even (items: List[int]) -> int: """Return the first even number from items. Return -1 if items contains no even numbers. >>> first_even([5, 8, 3, 2]) >>> first even([7, 1])
