input: Write a python function to filter elements with even length from a list of strings.
  assert even_length_elements(["hello", "world", "python", "code"]) == ["code"]
  assert even_length_elements(["test", "function", "example", "assert"]) == ["test", "function", "example"]
  assert even_length_elements(["a", "ab", "abc", "abcd"]) == ["ab", "abcd"]
output: def even_length_elements(strings):
      return [s for s in strings if len(s) % 2 == 0]
