如何在SQL表中返回值？

Question

我有一个Discord.py经济项目，如何在这个SQL表中选择exp并将其返回给嵌入数据库中的用户

代码：

@commands.command()
async def balance(self, ctx):
    db = sqlite3.connect('banco.sqlite')
    cursor = db.cursor()
    cursor.execute(f'SELECT user_id, exp, lvl FROM levels WHERE guild_id = {ctx.author.guild.id} AND user_id = {ctx.author.id}')
    result1 = cursor.fetchone()
    exp = int(result1[1])
        
    for i in range(1,99):
        if exp == i :
            em = discord.Embed(title = f'{ctx.author.name}', color = (0xbbbbbb))
            em.add_field(name = 'LOJINHA 2.0 ',value = int(result1[3]) )
            em.add_field(name = 'LOJINHA 2.0',value = 'C')
            em.set_author(name='LOJINHA 2.0', icon_url='https://i.imgur.com/X4u3yOW.png') 
            em.set_thumbnail(url='https://i.imgur.com/f05uKPn.png')  
            await ctx.send(embed = em)

我可能需要这一行代码的帮助：

         em.add_field(name = 'LOJINHA 2.0 ',value = int(result1[3])

我得到这个错误：
