sqlite3 无法让数据库保持更新

Question

这是供不和谐机器人存储用户游戏数据的。只要机器人永远不会关闭，它就可以工作，但如果我关闭它，它会重新初始化数据库。我尝试注释掉初始用户插入，类似于注释掉创建数据库本身的方式，但这会导致第 57 行中对“行”的引用无法正常工作。

import discord
import os
import sqlite3

conn = sqlite3.connect('test.db')
print("Opened database successfully")

#CREATED DATABASE

    #     LEVEL            INT      NOT NULL,
    #     CP               INT,

#print ("Table created successfully")

#INSERT USER

您似乎从未commit您的书面数据。在插入后执行conn.commit() 或将您的连接isolation_level 设置为None。
