如何使用Python连接MySQL表的列值？
MySQL is an open−source relational database management system that is widely used to store, manage, and organize data. When working with MySQL tables, it is common to require the combination of multiple column values into a single string for reporting and analysis purposes. Python, a high−level programming language, offers several libraries that enable connection to MySQL databases and execution of SQL queries.
在本文中，我们将深入探讨使用Python和PyMySQL库连接到MySQL数据库的过程，以及如何连接列值并使用Python打印结果的步骤指南。这种技术对于需要将多个列的值合并为一个字符串的MySQL数据库的数据分析师和开发人员特别有用。
