好的！下面是一个简单的基于列表实现的通讯录管理系统示例。这段代码展示了如何使用 Python 列表进行基本的增、删、查、改操作。

class Contact:  
    def __init__(self, name, phone, email):  
        self.name = name  
        self.phone = phone  
        self.email = email  
    def __str__(self):  
        return f"Name: {self.name}, Phone: {self.phone}, Email: {self.email}"  
class AddressBook:  
    def __init__(self):  
        self.contacts = []  
    def add_contact(self, name, phone, email):  
        new_contact = Contact(name, phone, email)  
        self.contacts.append(new_contact)  
        print(f"Contact {name} added successfully.")  
    def remove_contact(self, name):  
        for contact in self.contacts:  
            if contact.name == name:  
                self.contacts.remove(contact)  
                print(f"Contact {name} removed successfully.")  
                return  
        print(f"Contact {name} not found.")  
    def update_contact(self, name, phone=None, email=None):  
        for contact in self.contacts:  
            if contact.name == name:  
                if phone:  
                    contact.phone = phone  
                if email:  
                    contact.email = email  
                print(f"Contact {name} updated successfully.")  
                return  
        print(f"Contact {name} not found.")  
    def find_contact(self, name):  
        for contact in self.contacts:  
            if contact.name == name:  
                print(contact)  
                return  
        print(f"Contact {name} not found.")  
    def list_contacts(self):  
        if not self.contacts:  
            print("Address book is empty.")  
        for contact in self.contacts:  
            print(contact)  
def main():  
    address_book = AddressBook()  
    while True:  
        print("\nAddress Book Menu:")  
        print("1. Add Contact")  
        print("2. Remove Contact")  
        print("3. Update Contact")  
        print("4. Find Contact")  
        print("5. List Contacts")  
        print("6. Exit")  
        choice = input("Please enter your choice: ")  
        if choice == '1':  
            name = input("Enter name: ")  
            phone = input("Enter phone: ")  
            email = input("Enter email: ")  
            address_book.add_contact(name, phone, email)  
        elif choice == '2':  
            name = input("Enter name of the contact to remove: ")  
            address_book.remove_contact(name)  
        elif choice == '3':  
            name = input("Enter name of the contact to update: ")  
            phone = input("Enter new phone (or press enter to skip): ")  
            email = input("Enter new email (or press enter to skip): ")  
            address_book.update_contact(name, phone if phone else None, email if email else None)  
        elif choice == '4':  
            name = input("Enter name of the contact to find: ")  
            address_book.find_contact(name)  
        elif choice == '5':  
            address_book.list_contacts()  
        elif choice == '6':  
            print("Exiting the Address Book.")  
            break  
        else:  
            print("Invalid choice. Please try again.")  
if __name__ == "__main__":  
    main()  

功能说明
