Question

所以我有一些看起来像这样的代码：

import discord, asyncio

client = discord.Client()

@client.event
async def on_member_update(preupd, postupd):
    if postupd.server.id == '1234' and postupd.permissions_in(client.get_channel('5')).read_messages == True:
        embed = discord.Embed(title="Test", colour=0xFF000)
        embed.add_field(name="Test", value="Test <#5>")
        await client.send_message(client.get_channel('5'), embed=embed)
    if postupd.server.id == '1234' and postupd.permissions_in(client.get_channel('6')).read_messages == True:
        embed = discord.Embed(title="Test", colour=0xFF000)
        embed.add_field(name="Test", value="Test <#6>")
        await client.send_message(client.get_channel('6'), embed=embed)
    if postupd.server.id == '1234' and postupd.permissions_in(client.get_channel('7')).read_messages == True:
        embed = discord.Embed(title="Test", colour=0xFF000)
        embed.add_field(name="Test", value="Test <#7>")
        await client.send_message(client.get_channel('7'), embed=embed)
    if postupd.server.id == '1234' and postupd.permissions_in(client.get_channel('8')).read_messages == True:
        embed = discord.Embed(title="Test", colour=0xFF000)
        embed.add_field(name="Test", value="Test <#8>")
        await client.send_message(client.get_channel('8'), embed=embed)

client.run('ClientTokenHere')

正如你所看到的，我复制/粘贴了几乎相同的东西4次，但细节略有不同。所以我尝试通过制作这样的函数来缩短代码：

import discord, asyncio

client = discord.Client()

@client.event
async def on_member_update(preupd, postupd):
    async def shorter(numba):
        if postupd.server.id == '1234' and postupd.permissions_in(client.get_channel(str(numba))).read_messages == True:
            embed = discord.Embed(title="Test", colour=0xFF000)
            embed.add_field(name="Test", value="Test <#%s>" % numba)
            await client.send_message(client.get_channel(str(numba)), embed=embed)

    shorter('5')
    shorter('6')
    shorter('7')
    shorter('8')

client.run('ClientTokenHere')

然而，这给了我一个错误：myfile.py:35: RuntimeWarning: coroutine 'on_member_update.<locals>.perms' was never awaited，即使我在顶部运行“更长”的版本代码，一切运行顺利。显然我在某种程度上错误地定义了函数。我怎样才能解决这个问题？或者，还有更好的方法？感谢

您也可以这样做：

import discord, asyncio

client = discord.Client()

@client.event
async def on_member_update(preupd, postupd):
    for numba in ('5', '6', '7', '8'):
        if postupd.server.id == '1234' and postupd.permissions_in(client.get_channel(str(numba))).read_messages == True:
            embed = discord.Embed(title="Test", colour=0xFF000)
            embed.add_field(name="Test", value="Test <#%s>" % numba)
            await client.send_message(client.get_channel(str(numba)), embed=embed)

client.run('ClientTokenHere')

如何缩短此代码（复制/粘贴相同的行多次）？
