pymsql连接池的python代码

答案可以参考下面这段代码：import pymysql# 创建连接池对象
connection_pool = pymysql.connect(
host = 'localhost',
user = 'username',
password = 'password',
db = 'dbname',
charset = 'utf8',
port = 3306
)# 从连接池中获取一个连接
connection = connection_pool.get_connection()# 执行数据库操作
cursor = connection.cursor()
cursor.execute("SELECT * FROM table")# 关闭连接
connection.close()
