Pressing Enter with no input value on the course name will exit the loop, close the file, print "File was created and closed" and return the bool value True to the main().  See Simple GPA Tip below. retrieve()  will open and read grades.txt. The function then will print the course names and  Class GPA as shown below. The average of all class  GPA values should be calculated and displayed  to two decimal places and then return variable used for the GPA average to the main() .
