how to get your iq

def iq_test(numbers):
    nums = numbers.split(" ")
    evens = []
    odds = []
    for num in nums:
        if num % 2 == 0:
            evens.append(num)
        else:
            odds.append(num)
        if len(evens) > len(odds):
            return nums.index(odds[0]) + 1
        else:
            return nums.index(evens[0]) + 1
