What does the following program do? student = 1 while student <= 3: total = 0 for score in range (1,4): score = int(input("En
ter test score: ")) total += score average = total/3 print("Student ", student, "average: ", average) student += 1
1 answer:
Answer:
The code requests for the scores of three students for three courses offered by each student.
It calculates and print the average score for each student
Explanation:
The code written in Python programming language uses a while to get student 1-3 and a for loop to get scores for course 1-3
