Define a Python function named count_primes that consumes two int arguments start and stop and returns the number of prime integers between start (inclusive) and stop (exclusive).   You may assume that start will be less than stop and that they are both ints. You may use the pre-defined function named is_prime which consumes a positive number and returns True if the number is prime and False if the number is not prime. For example: Test Result print(count_primes(10,20)) 4
