字典可变格式化

Question

我想要使用MySQLdb的INSERT语句解释变量在Python 2.7：

cursor.execute("INSERT INTO DCPOWERSTATS(TS,TOTALPOWER,ITPOWER,AVAILABLEPOWER,PuE) VALUES (%s %s %s %s %s)",(dict_timestamp[key], dict_ABFeeds[key], dict_ABITLOAD[key], 1400, PuE)) 

和表：

sql_createpowertable = '''CREATE TABLE IF NOT EXISTS DCPOWERSTATS (TS DATETIME ,TOTALPOWER FLOAT,ITPOWER FLOAT, AVAILABLEPOWER FLOAT, PuE FLOAT)''' 

cursor.execute(sql_createpowertable) . 

当我尝试这个，我得到错误：

_mysql_exceptions.ProgrammingError: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '483.9 334.4 1400 1.44706937799043)' at line 1") 

Answer 1

在插入语句中，每个%s之后需要逗号：

INSERT INTO DCPOWERSTATS(TS,TOTALPOWER,ITPOWER,AVAILABLEPOWER,PuE) VALUES (%s, %s, %s, %s, %s)
