Python代码怎么编写一个通信录管理系统(具有增加、修改、删除、查询等功能）。

您好！感谢您对ChitGPT的信任和使用。针对您的问题，如下是一个简单的Python代码实现：

#通讯录管理系统

class AddressBook:
    
    def __init__(self):
        self.contacts = {}
        
    def add_contact(self, name, phone_number, email_address):
        self.contacts[name] = {'Phone Number': phone_number, 'Email Address': email_address}
        print('{} has been added to the address book!'.format(name))
        
    def update_contact(self, name, phone_number=None, email_address=None):
        if name in self.contacts:
            if phone_number is not None:
                self.contacts[name]['Phone Number'] = phone_number 
            if email_address is not None:
                self.contacts[name]['Email Address'] = email_address
            print('{}\'s contact information has been updated!'.format(name))
        else:
            print('Sorry, {} is not in the address book.'.format(name))
    
    def delete_contact(self, name):
        if name in self.contacts:
            del self.contacts[name]
            print('{} has been deleted from the address book!'.format(name))
        else:
            print('Sorry, {} is not in the address book.'.format(name))
    
    def search_contact(self, name):
        if name in self.contacts:
            print('{}\'s contact information:\nPhone Number: {}\nEmail Address: {}'.format(
                name, self.contacts[name]['Phone Number'], self.contacts[name]['Email Address']))
        else:
            print('Sorry, {} is not in the address book.'.format(name))

#测试
my_address_book = AddressBook()

#添加联系人
my_address_book.add_contact('Tom', '1234567890', 'tom@example.com')
my_address_book.add_contact('Lisa', '0987654321', 'lisa@example.com')

#更新联系人
my_address_book.update_contact('Tom', phone_number='1111111111')
my_address_book.update_contact('David', phone_number='2222222222')

#删除联系人
my_address_book.delete_contact('Lisa')
my_address_book.delete_contact('Mike')

#查询联系人
my_address_book.search_contact('Tom')
my_address_book.search_contact('Lisa')

代码说明：

- AddressBook类是一个通讯录管理系统，保存在内存中，使用字典数据结构实现；
- add_contact方法接收3个参数：联系人姓名、电话号码、电子邮件地址，将联系人信息添加到通讯录；
- update_contact方法接收3个参数：联系人姓名、电话号码、电子邮件地址，根据参数更新联系人信息；
- delete_contact方法接收1个参数：联系人姓名，根据参数删除联系人；
- search_contact方法接收1个参数：联系人姓名，根据参数查询联系人信息。

祝您编写愉快！
