不会从mysql中删除数据。还有其他方法可以做到吗？

Question

我正在尝试使用pymysql从mysql数据库中删除一些记录，但是我无法执行。如果我在mysql中执行它的工作，则使用相同的命令。

logger = logging.getLogger()
logger.setLevel(logging.INFO)

# Connect to the MYSQL database
logger.info("Connecting to MySQL database")
try:
    conn = pymysql.connect(host=rds_host, user=name, passwd=password, database=db_name, cursorclass=pymysql.cursors.DictCursor)
    cur = conn.cursor()
except:
    logger.error("ERROR: Unexpected error: Could not connect to MySql instance.")
    sys.exit()

logger.info("SUCCESS: Connection to MySQL database succeeded")

def _clean_general_logs():
    cur.execute(
        "DELETE FROM desker.general_log WHERE event_time <= '2019-08-12 04:36:42.457536' ORDER BY event_time DESC limit 10")
    conn.commit()
    cur.close()
    conn.close()
    return {"result": True}
