python学生信息管理系统简易版

以下是一个简易版的Python学生信息管理系统的示例：

class Student:
    def __init__(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)
                break

    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"

    def get_all_students(self):
        student_info = ""
        for student in self.students:
            student_info += f"Name: {student.name}, Age: {student.age}, Grade: {student.grade}\n"
        return student_info

# 创建学生信息管理系统对象
sms = StudentManagementSystem()

# 添加学生信息
sms.add_student("Alice", 18, "A")
sms.add_student("Bob", 17, "B")
sms.add_student("Charlie", 16, "C")

# 获取指定学生信息
print(sms.get_student_info("Alice"))  # 输出：Name: Alice, Age: 18, Grade: A

# 移除学生信息
sms.remove_student("Bob")

# 获取所有学生信息
print(sms.get_all_students())
# 输出：
# Name: Alice, Age: 18, Grade: A
# Name: Charlie, Age: 16, Grade: C
