Within the function, we create an empty list primes to store the prime numbers that will be found. A for loop is used to iterate through all the numbers within the range from lower to upper 1. For each number, we first check if it is greater than 1 since all prime numbers are greater than 1, then we use another for loop to iterate through all the possible factors of the number from 2 to num 2 1. If the number is divisible by any of these potential factors i.e. num i 0, then we break out of the inner for loop, meaning the number is not a prime. Otherwise, if the inner for loop completes without finding any factors, the number is a prime, and we append it to the primes list. Finally, we return the list of prime numbers. To use this function, we define the range we are interested in from 4 to 20 in this case, call the function with lower and upper as arguments, and print the result.
