我正在为学生构建出勤应用程序。他们将输入学生证，并将其姓名从“缺席”列表中删除。如果它们很慢，则会将其名称添加到其他列表中，并显示它们很慢。该应用程序取决于时间和特定学生所在的班级-现在，如果它在第一小时的开始和结束之间，则应用程序的标题为1st Hour，并显示第一小时的花名册。如果我在第一个小时结束后重新初始化，它将给我第二个小时。我需要它在第一个小时结束时自动切换到第二个小时，而无需重新启动程序。
我到处都是互联网，包括Stack上的许多类似帖子，并且尝试了对我的问题有意义的每个答案，但是我尝试的所有操作都给了我一个错误，并且查找错误要么导致与我的需求无关或我不了解的事情（我只做了几周）。挫败感使我不得不发布自己的代码来寻求帮助。

同样，除了时间/课程时间的自动更新以外，在所有方面的输出都完全符合要求。我同意可能有更高效/更清洁的方法来完成我已经做过的事情-我很想了解这一点-但我现在的首要任务是弄清楚难题的最后一部分，以便我继续开学前去做其他事情。感谢您的帮助！
