如何在discord.py中更新变量

import discord
from discord.ext import commands

client = commands.Bot(command_prefix='!')

@client.event
async def on_message(message):
    if message.author.bot:
        return  # 忽略机器人自己的消息

    if message.content.startswith('!update_var'):
        # 从消息中提取新值，例如通过消息内容或者提及的方式
        new_value = ...

        # 更新相应的变量
        my_variable = new_value

        await message.channel.send('变量已更新！')

client.run('YOUR_BOT_TOKEN')

import discord
from discord.ext import commands, tasks

client = commands.Bot(command_prefix='!')

@tasks.loop(minutes=5)
async def update_variable():
    # 从API获取新值，例如使用requests库发送HTTP请求获取数据
    new_value = ...

    # 更新相应的变量
    my_variable = new_value

@client.event
async def on_ready():
    update_variable.start()  # 启动定时任务

client.run('YOUR_BOT_TOKEN')

import discord
from discord.ext import commands

client = commands.Bot(command_prefix='!')

my_variable = 0  # 定义全局变量

@client.event
async def on_message(message):
    global my_variable  # 声明对全局变量的引用
    if message.content == '!update_var':
        my_variable += 1
        await message.channel.send('变量已更新！')

@client.event
async def on_ready():
    await client.change_presence(activity=discord.Game(name='My Variable: {}'.format(my_variable)))

client.run('YOUR_BOT_TOKEN')
