# 使用示例
contacts = ContactsList()
contacts.add_contact("Alice", "12345")
contacts.add_contact("Bob", "67890")
contacts.show_contacts()
contacts.search_contact("Alice")
contacts.delete_contact("Alice")
contacts.update_contact("Bob", "54321")
contacts.show_contacts()这段代码定义了Contact和ContactsList两个类，分别用于表示单个联系人和通讯录列表。通过添加、显示、搜索、删除和更新联系人的方法，实现了一个简单的通讯录管理系统。
