用python代码实现- name: string - email: string + get_info(): string } class Student { - courses: List<Course> + add_course(course: Course) + remove_course(course: Course) + get_courses(): List<Course> + get_info(): string } class Teacher { - courses: List<Course> + add_course(course: Course) + remove_course(course: Course) + get_courses(): List<Course> + get_info(): string } class Admin { + add_student(student: Student) + remove_student(student: Student) + add_teacher(teacher: Teacher) + remove_teacher(teacher: Teacher) + add_course(course: Course) + remove_course(course: Course) } class Course { - name: string - teacher: Teacher - students: List<Student> + get_info(): string } Student *-- Course Teacher *-- Course Course "1"--o "1" Teacher Course "1"--o "1..*" Student Admin ..> Person Person <|-- Student Person <|-- Teacher Person <|-- Admin

以下是实现该类的Python代码：

from typing import List

class Person:
    def __init__(self, name: str, email: str):
        self.name = name
        self.email = email
        
    def get_info(self) -> str:
        return f"Name: {self.name}\nEmail: {self.email}"
    
class Student(Person):
    def __init__(self, name: str, email: str):
        super().__init__(name, email)
        self.courses = []
        
    def add_course(self, course):
        self.courses.append(course)
        
    def remove_course(self, course):
        self.courses.remove(course)
        
    def get_courses(self) -> List[str]:
        return [course.name for course in self.courses]
    
    def get_info(self) -> str:
        return f"{super().get_info()}\nCourses: {', '.join(self.get_courses())}"
    
class Teacher(Person):
    def __init__(self, name: str, email: str):
        super().__init__(name, email)
        self.courses = []
        
    def add_course(self, course):
        self.courses.append(course)
        
    def remove_course(self, course):
        self.courses.remove(course)
        
    def get_courses(self) -> List[str]:
        return [course.name for course in self.courses]
    
    def get_info(self) -> str:
        return f"{super().get_info()}\nCourses: {', '.join(self.get_courses())}"
    
class Admin:
    def __init__(self):
        self.students = []
        self.teachers = []
        self.courses = []
        
    def add_student(self, student: Student):
        self.students.append(student)
        
    def remove_student(self, student: Student):
        self.students.remove(student)
        
    def add_teacher(self, teacher: Teacher):
        self.teachers.append(teacher)
        
    def remove_teacher(self, teacher: Teacher):
        self.teachers.remove(teacher)
        
    def add_course(self, course):
        self.courses.append(course)
        
    def remove_course(self, course):
        self.courses.remove(course)
        
class Course:
    def __init__(self, name: str, teacher: Teacher):
        self.name = name
        self.teacher = teacher
        self.students = []
        
    def add_student(self, student: Student):
        self.students.append(student)
        
    def remove_student(self, student: Student):
        self.students.remove(student)
        
    def get_info(self) -> str:
        return f"Name: {self.name}\nTeacher: {self.teacher.name}\nStudents: {[student.name for student in self.students]}"
        
# Example Usage
admin = Admin()
teacher = Teacher("John Smith", "john.smith@example.com")
course = Course("Math", teacher)
student = Student("Jane Doe", "jane.doe@example.com")
admin.add_teacher(teacher)
admin.add_student(student)
admin.add_course(course)
course.add_student(student)
teacher.add_course(course)
student.add_course(course)

print(student.get_info())
print(teacher.get_info())
print(course.get_info())
