Question

我正在编写一个执行以下操作的简单代码：

显示现有SQL数据库中的表
如果数据库包含名为“ temp”的表，请删除临时表
如果数据库不包含名为“ temp”的表，请创建临时表
显示现在在SQL数据库中的表

所以基本上，这只是打开和关闭'temp'表，这是代码：

import os
import sqlite3

dbPath = '......\\DB.db'

conn = sqlite3.connect(dbPath)
cur = conn.cursor()

cur.execute('SELECT * FROM sqlite_master')
tableList = []
for sql_type, sql_name, tbl_name, rootpage, sql in cur.fetchall():
    if sql_type == 'table':
        tableList.append(sql_name)
print('Tables currently in DB: ' + ', '.join(tableList))

if 'temp' in tableList:
    cur.execute('DROP TABLE temp')
    conn.commit()
    print('temp table deleted')
else:
    cur.execute('CREATE TABLE temp AS SELECT * FROM data')
    conn.commit()
    print('temp table created')

cur.execute('SELECT * FROM sqlite_master')
tableList = []
for sql_type, sql_name, tbl_name, rootpage, sql in cur.fetchall():
    if sql_type == 'table':
        tableList.append(sql_name)
print('Tables now in DB: ' + ', '.join(tableList))

conn.close()

当我在VS Code中运行它时，它完成了我想要的一切，但通常以以下EOF错误结尾：

Traceback (most recent call last):

EOFError

当我通常说时，我的意思是大约90％的时间里，这种不一致对我来说很奇怪又很新。它一定意味着什么，对吧？

我已注释掉多行内容，并修改了我能想到的所有内容，以查看它是否消失了。

谢谢！
