用python做一个可操作性的增删改查学生管理系统+ 源码可直接运行

以下就是源码:

# 定义学生类
class Student:
    def __init__(self, id, name, age):
        self.id = id
        self.name = name
        self.age = age

# 初始化学生列表
students = [
    Student(1, 'Tom', 18),
    Student(2, 'Jerry', 19),
    Student(3, 'Alice', 20)
]

# 添加学生
def add_student():
    id = int(input('请输入学生ID：'))
    name = input('请输入学生姓名：')
    age = int(input('请输入学生年龄：'))
    student = Student(id, name, age)
    students.append(student)
    print('添加成功！')

# 删除学生
def delete_student():
    id = int(input('请输入要删除的学生ID：'))
    for student in students:
        if student.id == id:
            students.remove(student)
            print('删除成功！')
            return
    print('找不到该学生！')

# 修改学生
def modify_student():
    id = int(input('请输入要修改的学生ID：'))
    for student in students:
        if student.id == id:
            name = input('请输入学生姓名：')
            age = int(input('请输入学生年龄：'))
            student.name = name
            student.age = age
            print('修改成功！')
            return
    print('找不到该学生！')

# 查询学生
def query_student():
    id = int(input('请输入要查询的学生ID：'))
    for student in students:
        if student.id == id:
            print('学生ID：', student.id)
            print('学生姓名：', student.name)
            print('学生年龄：', student.age)
            return
    print('找不到该学生！')

#展示学生信息
def show_student():
    for student in students:
        print('学生ID：', student.id,'学生姓名：', student.name,'学生年龄：', student.age)
    return



# 显示菜单
def show_menu():
    print('1. 添加学生')
    print('2. 删除学生')
    print('3. 修改学生')
    print('4. 查询学生')
    print('5. 显示信息')
    print('6. 退出系统')

# 主函数
def main():
    while True:
        show_menu()
        choice = int(input('请选择操作：'))
        if choice == 1:
            add_student()
        elif choice == 2:
            delete_student()
        elif choice == 3:
            modify_student()
        elif choice == 4:
            query_student()
        elif choice == 5:
            show_student()
        elif choice == 6:
            break
        else:
            print('无效的选择！')

if __name__ == '__main__':
    main()
