MySQLdb executemany使用列表作爲輸入？

Question

我想用我的計劃內的executemany存儲20條記錄一次，繼承人它在文檔中說...

c.executemany(
    """INSERT INTO breakfast (name, spam, eggs, sausage, price) 
    VALUES (%s, %s, %s, %s, %s)""", 
    [ 
    ("Spam and Sausage Lover's Plate", 5, 1, 8, 7.95), 
    ("Not So Much Spam Plate", 3, 2, 0, 3.95), 
    ("Don't Wany ANY SPAM! Plate", 0, 4, 3, 5.95) 
    ]) 

不過，我在列表中有我的價值觀，而寧可不要做18個以上的版本，在我的列表中使用索引。

這裏是我的代碼如下...

db = connect_to_db() 
cursor = db.cursor() 
sql = "INSERT INTO gkey (keyword, date, time, position) VALUES (%s, %s, %s, %s)" 
params = [(str(keywords[0]), date, time, position[0])] 
cursor.executemany(sql, params) 
db.commit() 

這工作得很好，並且它會犯的第一個關鍵字列表，與日期，時間和位置一起，我不希望有重複PARAMS 19次象下面...

db = connect_to_db() 
cursor = db.cursor() 
sql = "INSERT INTO gkey (keyword, date, time, position) VALUES (%s, %s, %s, %s)" 
params = [ 
(str(keywords[0]), date, time, position[0]) 
(str(keywords[0]), date, time, position[0]) 
(str(keywords[0]), date, time, position[0]) 
(str(keywords[0]), date, time, position[0]) 
(str(keywords[0]), date, time, position[0]) 
(str(keywords[0]), date, time, position[0]) 
(str(keywords[0]), date, time, position[0]) 
(str(keywords[0]), date, time, position[0]) 
(str(keywords[0]), date, time, position[0]) 
(str(keywords[0]), date, time, position[0]) 
(str(keywords[0]), date, time, position[0]) 
(str(keywords[0]), date, time, position[0]) 
(str(keywords[0]), date, time, position[0]) 
(str(keywords[0]), date, time, position[0]) 
(str(keywords[0]), date, time, position[0]) 
(str(keywords[0]), date, time, position[0]) 
(str(keywords[0]), date, time, position[0])  
(str(keywords[0]), date, time, position[0]) 
(str(keywords[0]), date, time, position[0]) 

] 
cursor.executemany(sql, params) 
db.commit() 

上面的什麼，我想避免一個例子（索引需要遞增它的工作，我知道！;））

我得到一個錯誤當我嘗試將整個列表作爲一個值傳遞時，我需要一次一個地傳遞它們，有什麼想法？可以執行很多操作，還是應該循環更新一次？但我敢肯定，我嘗試過，並有類似的錯誤？雖然我沒有注意到它。

Answer 1

params = [(str(keywords[i]), date, time, position[i]) for i in range(20)]
