Background
The modulus operator is used to find the remainder computed from integer division. For example, 5384 divided by 4 will return the value 1 because when you divide 53 by 4 using long division, you will see a remainder of 1. Another way to see this is that 53 is 1 more than a multiple of 4. Test out several values using the operator. A prime number is a positive integer greater than 1 whose only divisors are 1 and itself. That is, a prime number only has two divisors: 1 and the number itself. Do this: Use control flow and the modulus operator to count how many prime numbers there are in the list of odd numbers below:
odd_numbers = [1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29]
