大家好，所以基本上，我试图完成一项编程任务，但似乎需要一些备份。
这是我现在拥有的3个代码文件：

如果我在程序运行时输入1，它应该显示当前学生的所有信息。
如果我输入2，它会问我你想搜索的主题是什么。一旦我进入
如果我输入3，它应该按天(从周一到周五(搜索，并列出匹配日期的学生。
如果我输入4，它应该通过输入他们的姓名、年级和科目来添加一名导师。
如果我输入5，它应该通过输入姓名将导师从辅导列表中删除。
如果我输入6，它应该询问我想向谁添加辅导课时，以及我总共想添加多少课时。
如果我输入7，它应该显示老师的名字、活跃导师的数量和辅导的总小时数。
选项1没有打印出任何内容(这是我试图解决的最基本的问题(，除此之外，选项2和选项3也有同样的问题。4、5和6无法完全测试，因为选项1无法发挥作用。所以，从我现在看到的情况来看，只有7个在工作。(Bruh(
此外，选项4中还有一个问题：如果你没有输入9-12之间的数字来定义新导师的分数，那么不会弹出通知你没有按照指示操作的消息。
有人愿意给我一些指示吗？
编辑：选项1出现错误，问题中未包含该选项。我真诚的道歉。
您的问题不包括回溯，但当我运行代码时，我得到了：

string += "nGrade:", self.grade
TypeError: can only concatenate str (not "tuple") to str
它将我们指向您的__str__功能之一：
def __str__(self):
string = ""
string += self.name
string += "nGrade:", self.grade
string += "nSubjects:", self.subjects
string += "nDays:", self.days
string += "nHours:", self.hours
return string
正如错误所说，您不能将元组连接(添加(到str——像"nGrade:", self.grade这样的表达式是(str和int的(元组。
我建议做一些类似的事情：
def __str__(self):
return f"""{self.name}
Grade: {self.grade}
Subjects: {self.subjects}
Days: {self.days}
Hours: {self.hours}"""
或者，如果你想得到幻想：
def __str__(self):
return "n".join(f"{a.title()}: {v}" for a, v in self.__dict__.items())
这至少修复了你的"；选项1"；错误对于其他错误，请确保您正在查看代码引发的异常，然后查看代码和错误消息，以找出代码产生该错误的原因。
