今年教师节前夕，我特意用Python做了个学生点名系统，非常好用，送给各科老师、辅导员当节日礼物，老师们都喜滋滋，说平常逃课就原谅我了，我心想，这次毕业应该不是问题了~
本文背景
根据我的调查，大多数学生都很活跃，会主动举手回答问题。但也会出现一些不好的情况，比如年级越高，主动举手的人越少，一些班级平时举手的都是少数积极的学生，有些学生从来不举手。
[En]
According to my survey, most of the students are very active and will take the initiative to raise their hands to answer questions. However, there will also be some bad situations, such as the higher the grade, the fewer people take the initiative to raise their hands, some classes usually raise their hands are usually a small number of positive students, some students never raise their hands.
所以我做了一个随机点名系统来帮助老师解决这些问题。
[En]
So I made a random student roll call system to help teachers solve these problems.
- 随机点名将从全班随机抽取一名学生，让每个人都有机会回答问题，促进教育公平。
[En]
A random roll call will randomly select a student from the whole class, so that everyone will have the opportunity to answer questions and promote educational fairness.*
- 点名系统有几秒钟的滚动时间，会增加学生的紧张情绪，让被遗弃的学生迅速集中注意力，发挥监督学习的作用。
[En]
the roll call system has a rolling time of a few seconds, which will increase the tension of the students and let the deserted students concentrate quickly and play a role in supervising their study.*
- 如果真的没有学生举手，老师也没必要尴尬。点名系统可以成为老师们的一大杀手锏。
[En]
if there are really no students raising their hands, there is no need for teachers to be embarrassed. The roll call system can be used as a "killer mace" for teachers.*
在实际情况中，部分时间可以依靠学生主动，部分时间使用点名系统，灵活使用。
[En]
In the actual situation, part of the time can rely on students to take the initiative, part of the time to use the roll call system, flexible use.
