python学生管理系统代码及其界面

这里提供一个简单的Python学生管理系统代码及其界面。请注意，这是一个基于命令行的系统，没有图形用户界面。

代码：

class Student:
    def __init__(self, name, age, grade):
        self.name = name
        self.age = age
        self.grade = grade

class StudentManager:
    def __init__(self):
        self.students = []
    
    def add_student(self, student):
        self.students.append(student)
    
    def remove_student(self, name):
        for student in self.students:
            if student.name == name:
                self.students.remove(student)
                return True
        return False
    
    def print_students(self):
        for student in self.students:
            print(f"Name: {student.name}, Age: {student.age}, Grade: {student.grade}")

manager = StudentManager()

while True:
    print("\nWelcome to the Student Management System")
    print("1. Add Student")
    print("2. Remove Student")
    print("3. View Students")
    print("4. Exit")
    choice = input("Enter your choice: ")
    
    if choice == "1":
        name = input("Enter the student's name: ")
        age = int(input("Enter the student's age: "))
        grade = int(input("Enter the student's grade: "))
        student = Student(name, age, grade)
        manager.add_student(student)
        print(f"{name} added to the system.")
    
    elif choice == "2":
        name = input("Enter the student's name: ")
        if manager.remove_student(name):
            print(f"{name} removed from the system.")
        else:
            print(f"{name} not found in the system.")
    
    elif choice == "3":
        manager.print_students()
    
    elif choice == "4":
        print("Thank you for using the Student Management System.")
        break
    
    else:
        print("Invalid choice. Please try again.")
