一、测试成绩平均值计算程序

在Python编程中，我们常常需要处理各种数据，计算学生的测试成绩平均值就是一个常见的需求。下面是一个用于计算学生测试成绩平均值的程序：

# This program averages test scores. It asks the user for the
# number of students and the number of test scores per student.

# Get the number of students.
num_students = int(input('How many students do you have? '))

# Get the number of test scores per student.
num_test_scores = int(input('How many test scores per student? '))

# Determine each student's average test score.
for student in range(num_students):
    # Initialize an accumulator for the test scores.
    total = 0.0

    # Display the student number.
    print(f'Student number {student + 1}')
    print('-----------------')

    # Get the student's test scores
