Write a Python function that counts the number of even numbers in a given list of integers. The function should take a list as an input and return the number of even numbers within that list. Example: count_evens([2, 3, 4, 5, 6]) # should return 3 (since there are three even numbers: 2, 4, 6) count_evens([23, 24, 25]) # should return 1 (since there is only one even number: 24)
