import csv, sqlite3

con = sqlite3.connect(":memory:")
cur = con.cursor()
cur.execute("CREATE TABLE TWITTER_HANDLE (twitter_handle TEXT);")

with open('/Users/hyunjincho/Desktop/twitter_handle.csv','r') as fin:
     reader = csv.reader(fin)
     dicts = ({'twitter_handle': line[0]} for line in reader)
     to_db = ((i['twitter_handle']) for i in dicts)
cur.execute('INSERT INTO TWITTER_HANDLE (twitter_handle)', to_db)
con.commit()

python在该行抛出错误

  cur.execute('INSERT INTO TWITTER_HANDLE (twitter_handle)', to_db)

错误信息是

   near ")": syntax error

我不知道为什么 python 会抛出这个错误，因为我在我的代码中没有看到任何错误。但由于我是 python 新手，很可能有一个我无法发现的错误。

编辑：以下是错误的完整追溯

        OperationalError                          Traceback (most recent call last)

   ---> 48 cur.execute('INSERT INTO TWITTER_HANDLE (twitter_handle)', to_db)
        49 con.commit()
        50

我认为语法应该是：

cur.execute('INSERT INTO TWITTER_HANDLE (twitter_handle) VALUES(?)', to_db)

其中?指的是参数to_db
