用python简一个写学生管理系统

当然可以！以下是一个简单的学生管理系统的Python代码例：

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

class StudentManagementSystem:
    def __init__(self):
        self.students = []

    def add_student(self, name, age, grade):
        student = Student(name, age, grade)
        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 get_student_info(self, name):
        for student in self.students:
            if student.name == name:
                return f"Name: {student.name}, Age: {student.age}, Grade: {student.grade}"
        return "Student not found"

# 创建学生管理系统对象
sms = StudentManagementSystem()

# 添加学生
sms.add_student("Alice", 18, 12)
sms.add_student("Bob", 17, 11)

# 获取学生信息
print(sms.get_student_info("Alice"))  # 输出：Name: Alice, Age: 18, Grade: 12

# 移除学生
sms.remove_student("Bob")

# 再次获取学生信息
print(sms.get_student_info("Bob"))  # 输出：Student not found

这个学生管理系统使用了两个类：`Student`表示学生对象，`StudentManagementSystem`表示学生管理系统。你可以通过调用`add_student`方法添加学生，通过调用`remove_student`方法移除学生，通过调用`get_student_info`方法获取学生信息。
