删除python列表中输入的行信息

好的，以下是一个简单的学生信息管理系统的Python实现：

# 定义一个学生类
class Student:
    def __init__(self, name, age, gender, id):
        self.name = name
        self.age = age
        self.gender = gender
        self.id = id

# 定义一个学生信息管理系统类
class StudentManagementSystem:
    def __init__(self):
        self.students = []

    # 添加学生信息
    def add_student(self, student):
        self.students.append(student)

    # 显示所有学生信息
    def show_all_students(self):
        for student in self.students:
            print(f"姓名：{student.name}，年龄：{student.age}，性别：{student.gender}，学号：{student.id}")

    # 根据学号查询学生信息
    def search_student_by_id(self, id):
        for student in self.students:
            if student.id == id:
                print(f"姓名：{student.name}，年龄：{student.age}，性别：{student.gender}，学号：{student.id}")
                return
        print("未找到该学生")

    # 根据学号修改学生信息
    def modify_student_by_id(self, id, name, age, gender):
        for student in self.students:
            if student.id == id:
                student.name = name
                student.age = age
                student.gender = gender
                print("修改成功")
                return
        print("未找到该学生")

    # 根据学号删除学生信息
    def delete_student_by_id(self, id):
        for student in self.students:
            if student.id == id:
                self.students.remove(student)
                print("删除成功")
                return
        print("未找到该学生")

    # 保存学生信息到文件
    def save_students_to_file(self, filename):
        with open(filename, "w") as f:
            for student in self.students:
                f.write(f"{student.name},{student.age},{student.gender},{student.id}\n")

    # 从文件中读取学生信息
    def load_students_from_file(self, filename):
        with open(filename, "r") as f:
            lines = f.readlines()
            for line in lines:
                fields = line.strip().split(",")
                name = fields[]
                age = int(fields[1])
                gender = fields[2]
                id = fields[3]
                student = Student(name, age, gender, id)
                self.add_student(student)

# 测试代码
if __name__ == "__main__":
    sms = StudentManagementSystem()
    sms.add_student(Student("张三", 18, "男", "001"))
    sms.add_student(Student("李四", 19, "女", "002"))
    sms.add_student(Student("王五", 20, "男", "003"))
    sms.show_all_students()
    sms.search_student_by_id("002")
    sms.modify_student_by_id("002", "小李", 20, "女")
    sms.show_all_students()
    sms.delete_student_by_id("003")
    sms.show_all_students()
    sms.save_students_to_file("students.txt")
    sms.load_students_from_file("students.txt")
    sms.show_all_students()

这个学生信息管理系统包含了添加学生信息、显示所有学生信息、根据学号查询学生信息、根据学号修改学生信息、根据学号删除学生信息、保存学生信息到文件和从文件中读取学生信息等功能。你可以根据自己的需求进行修改和扩展。
