# Ask the user to provide final exam marks of 10 students in Introduction to Computing course in  order to calculate the average. Use while loop for this purpose, and use break statement to exit the loop when an invalid input (e.g negative number) is given. Moreover, if marks greater than 100  are given, use continue statement to skip that number from average calculation.

student_marks = int(input('Enter the marks, use -1 to stop: '))
student_marks_counter = 1
total_marks = 0
while student_marks_counter <=10:
    student_marks = int(input('Enter the marks, use -1 to stop: '))
    if student_marks == -1:
        break
    if student_marks > 100:
        continue
    else:
        print('Student Marks = ', student_marks)
        total_marks += student_marks
        print('Total Marks', total_marks)
    student_marks_counter += 1
print('The average is', total_marks / 10 )
