Question

我正在制作一个函数，通过他的服务器昵称查找一个人，并用它来查找 SQLite 数据库中的数据。

TypeError: not all arguments converted during string formatting

当我测试它时，有 3 个人在线：我（不是所有者）、机器人和测试帐户，还有 3 个人离线。机器人除了我的帐户外看不到其他成员，因此只打印一个昵称然后显示错误。

import discord
import datetime
import sqlite3 as sql
from discord.ext import commands
...
#TOKEN and SQLite database lines
...
intents = discord.Intents.default()
intents.members = True

bot = commands.Bot(command_prefix = "{", intents = intents)

@bot.event
async def on_reaction_add(reaction, user):
if isinstance((reaction.message.channel), discord.channel.DMChannel): #it works only in private (DM) channels
    msg = reaction.message
    channel = msg.channel
    guild = bot.get_guild(769858357607399443) #it is a valid ID of the guild with the bot
    member = guild.get_member(user.id)
    emoji_count = reaction.count
    if emoji_count > 1:
        if reaction.emoji == "?":
            print("test")
        elif reaction.emoji == "?":
            await channel.send("Enter the person's nickname.")
            def check(m):
                return m.author.id == user.id
            answer = await bot.wait_for("message", check = check)
from there  for memb in guild.members:
                print(memb.nick)
                if memb.nick.lower() == answer.content.lower():
to there        member_act = memb
            cur.execute(f"SELECT * FROM users WHERE discord_user_id = 
            {member_act.id};")
            data_tuple = cur.fetchall()
            data = data_tuple[0]
            embed=discord.Embed(title="Name:", description=f" 
            {member_act.name}", color=0x0037f3)
            embed.set_author(name="PG Official Profile Card")
            embed.add_field(name = "nice")... 
            ... #just the rest of embed.
            await channel.send(embed = embed)

今天（一天后）机器人甚至没有打印我的帐户名，只有一个 Tony_Forlatt ### it is the nickname of my account None ### the reason of the error Ignoring exception in on_reaction_add Traceback (most recent call last): File "C:\Users\plays\AppData\Local\Programs\Python\Python38-32\lib\site-packages\discord\client.py", line 312, in _run_event await coro(*args, **kwargs) File "C:\Users\plays\OneDrive\Рабочий стол\Python\bot2.py", line 227, in on_reaction_add if memb.nick.lower() == answer.content.lower(): AttributeError: 'NoneType' object has no attribute 'lower'，然后是错误。为什么会发生这种情况，如何解决？

Answer 1

用memb.nick.lower()代替str(memb.nick).lower()

机器人看不到服务器上的成员
