如何使這段代碼更短（多次復制/粘貼同一行）？

Question

所以我有一些代碼看起來像這樣：

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')

如您所見，我將相同的內容復制/粘貼了4次，但細節稍有不同。 因此，我嘗試通過編寫如下函數來縮短代碼：

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')

但是，這給了我一個錯誤： myfile.py:35: RuntimeWarning: coroutine 'on_member_update.<locals>.perms' was never awaited : myfile.py:35: RuntimeWarning: coroutine 'on_member_update.<locals>.perms' was never awaited ，即使我在頂部運行“更長”版本代碼，一切也可以順利進行。 顯然，我以某種方式錯誤地定義了函數。 我怎樣才能解決這個問題？ 或者，還有更好的方法？ 謝謝

您還可以執行以下操作：

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')
