Question

我有一个问题。当我执行整个事情时，它会抛出一个错误说明：TypeError：没有足够的格式字符串参数。我想这与cur.execute中的错误有关（“INSERT INTO modules（module_name，no_of_scripts，gsm，exam_type，exam_date，school）VALUES（％s，％s，％s，％s，％s，％s）“）但不确定可能导致问题的原因。请帮助谢谢！

以下是参考代码：

 db = MySQLdb.connect(host='localhost',
                         user="schooluser",
                         passwd="",
                         db="exam_import")
    cur = db.cursor()
    csv_data = csv.reader(file('Modules.csv'))
    for row in csv_data:
        cur.execute("INSERT INTO `modules`(module_name, no_of_scripts, gsm, exam_type, exam_date, school) VALUES (%s, %s, %s, %s, %s, %s)")
    cur.execute("SELECT * FROM modules")
    for row in cur.fetchall():

            self.name = row[0]
            self.sheetsperpaper = row[1]
            self.paperweightlol = row[2]
            self.exam_type1 = row[3]
            self.exam_series1 = row[4]
            self.exam_school1 = row[5]

            self.module_name.append(self.name)
            self.sheets.append(self.sheetsperpaper)
            self.paperweight.append(self.paperweightlol)
            self.exam_type.append(self.exam_type1)
            self.exam_series.append(self.exam_series1)
            self.exam_school.append(self.exam_school1)

    db.commit()
    db.close()

您需要为查询设置值

λ Nothing : [ Just 1, Nothing ]
[Nothing,Just 1,Nothing]

所以你将行的每一列的值设置为你的查询（如果顺序不是那样，你可以改变行[x]的位置）
