制作一个拓展课自动点名系统Python语言编程怎么写

以下是一个简单的Python代码示例，用于制作一个拓展课自动点名系统：

import random

students = ["Alice", "Bob", "Charlie", "David", "Emily", "Frank", "Grace", "Henry", "Isabella", "John"]
present = []

def roll_call():
    global present
    present = []
    for i in range(3):
        student = random.choice(students)
        present.append(student)
        print("{}. {}".format(i+1, student))
    print("Please mark attendance for the above students.")

def main():
    while True:
        command = input("Enter a command (roll call, present, quit): ")
        if command == "roll call":
            roll_call()
        elif command == "present":
            print("Present students: {}".format(", ".join(present)))
        elif command == "quit":
            break
        else:
            print("Invalid command. Please try again.")

if __name__ == "__main__":
    main()

这个程序有三个主要功能：点名、显示出席学生名单和退出程序。点名功能将在学生列表中随机选择三个学生，并将他们的名字打印出来。显示出席学生名单功能将打印出最近一次点名时出席的学生名单。退出程序功能将结束程序运行。

为了使用这个程序，你需要将学生的名字列表替换为你班级的学生名字。你可以将这个程序保存在一个名为“extension_class.py”的文件中，并在终端中运行它，如下所示：

$ python extension_class.py
Enter a command (roll call, present, quit): roll call
1. Emily
2. Grace
3. Isabella
Please mark attendance for the above students.
Enter a command (roll call, present, quit): present
Present students: Emily, Grace, Isabella
Enter a command (roll call, present, quit): quit
