- 导入需要的模块：
python
import mysql.connector
- 定义表：
```python class Course: def init(self, name, coursename, departmentid, subjectid, learningrate, teacherid, students): self.name = name self.coursename = coursename self.departmentid = departmentid self.subjectid = subjectid self.learningrate = learningrate self.teacherid = teacher_id self.students = students
def __str__(self):
return f"Course(name={self.name}, course_name={self.course_name}, department_id={self.department_id}, subject_id={self.subject_id}, learning_rate={self.learning_rate}, teacher_id={self.teacher_id}, students={self.students})"
```
- 创建数据库：
python
Course = Course("Student1", "Student2", "Student3", "Student4", "Student5", "Student6", "Student7", "Student8")
- 添加课程：
python
Course.add_course("Student2")
Course.add_course("Student4")
Course.add_course("Student5")
Course.add_course("Student6")
- 添加学生：
python
Course.add_student("Student2")
- 查询课程表：
python
SELECT * FROM course
WHERE department_id = students.department_id
注意：上述代码中的“Students”是一个字典，其中每个键值对表示学生的信息。可以根据实际情况进行修改和调整。
