Python 3.x 还记得上次展示作业的3个学生吗

上次展示作业的3名学生。每次运行此程序时，它都会挑选一组新的3名学生。

假设给出了学生的卷号

students_roll_number = [1,2,3,4,5,6,7,8,9,10,11]

students_homework_showed = [3,4,5]

让那些还没拿出作业的学生

students_homework_pending = [students_roll_number[i] for i in  range(len(students_roll_number)) if students_roll_number[i] not in students_homework_showed]

输出为

students_homework_pending = [1, 2, 6, 7, 8, 9, 10, 11]

现在我们从候补名单中选出3名学生

students_to_check = []
for i in range(3): 
    students_homework_showed.append(students_homework_pending[i])
    students_to_check.append(students_homework_pending[i])

可供选择的新生

print("chosen student is : ", students_to_check)
