Python sqlite3操作E

Question

这是我的密码。它将以相同的格式读取一堆带有SQL命令的文件（例如，以-开头的注释，以及一些空行，因此在我的循环中有if条件）

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import csv,sqlite3,os

conn = sqlite3.connect('db_all.db')
c = conn.cursor()
files = os.listdir('C:\\Users\\ghb\\Desktop\\database_schema')

for file in files:
    string = ''
    with open(file, 'rb') as read:
        for line in read.readlines():
            if line[0]!='-' and len(line)!=0: string = string + line.rstrip() #error also occurs if I skip .rstrip
        print string #for debugging purposes
        c.executescript(string)
        string=''

conn.close()

错误：

^{pr2}$

为了避免混乱，这里是string变量的输出（没有INSERT INTO数据，这是机密的）：

SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO";
