Python code:

    for i in range(7): # loop to read 7 inputs
        print("Input scores ",i+1," : ", end="")  # a message to enter grade

        aGrades.append(n) # add grade into list
    print("Grade list before randomize: ",aGrades)   # print list 
    random.shuffle(aGrades) # randomize list
    numExams=len(aGrades)-1 # compute numExams
    FinalExam=aGrades[-1] # store final grade
    TotalPoints=sum(aGrades)-aGrades[-1]  # compute TotalPoints
    TestAverage=TotalPoints/numExams   # compute TestAverage
