Question
Write a Python program that prompts the user to enter grades to a list, alist (which is initially
empty), and calculate the sum and average of the entered grades. The user will continue
entering grades until he/she enters the sentinel value -1.
Important Notes:
- Grades are in the range from 0 to 20.
You should use the while loop to input the grades
You should print the final list, the sum, and the average (rounded to two figures).
One of the grades should be the last digit of your ID +10. For example, if your ID
number is 020787521426, then one of the entered grades should be 16 (6+10)
You should include screenshots of the code and the output.
Your program should have an output like the following:
In case no grades have been entered, the output should be:
Enter grades to calculate their average, -1 to stop entry: -1
No grades have been entered!
In case of entering some grades, the output should be:
Enter grades to calculate their average, -1 to stop entry: 13
Enter another grade, -1 to finish: 12
Enter another grade, -1 to finish: 18
Enter another grade, -1 to finish: -1
[13, 12, 18]
The Sum of the entered grades is: 43
The Average of the entered grades is: 14.33
