如何用Python和MySQL实现通讯录的数据库编程？

本文共计610个文字，预计阅读时间需要3分钟。

本文将分享一个Mysql实现通讯录的具体代码示例，供大家参考。

sql-- 创建通讯录表CREATE TABLE IF NOT EXISTS `address_book` ( `id` INT NOT NULL AUTO_INCREMENT, `name` VARCHAR(50) NOT NULL, `phone` VARCHAR(20) NOT NULL, `email` VARCHAR(50), PRIMARY KEY (`id`));

-- 插入示例数据INSERT INTO `address_book` (`name`, `phone`, `email`) VALUES('张三', '13800138000', 'zhangsan@example.com'),('李四', '13900139000', 'lisi@example.com'),('王五', '13700137000', 'wangwu@example.com');

-- 查询通讯录SELECT * FROM `address_book`;

-- 更新通讯录UPDATE `address_book` SET `phone`='13700013700' WHERE `name`='张三';

-- 删除通讯录DELETE FROM `address_book` WHERE `name`='李四';
