制作一个函数并通过message.channel.send发送

Question

试图从153减去消息中发送的数字

from discord.ext import commands

bot = discord.ext.commands.Bot(command_prefix = "$")

#the function
async def gamesAwayb1():
 return 153 - on_message() 
#not sure what to put instead of on_message

@bot.event

async def on_message(message):
  if 0 < int(message.content) < 153:
   await message.channel.send("you are in Bronze 1.  You are" , gamesAwayb1() , "games away from Bronze 2")


  if 153 < int(message.content) < 200:
   await message.channel.send("you are in Bronze 2")

忽略异常在on_messageTraceback（最近的调用最后）：文件"/opt/viralenvs/python3/lib/python3.8/site-包/不和谐/client.py"，第343行，在_run_event等待coro（*args，**kwargs）文件"main.py"，第13行，在on_message等待message.channel.send（“你在青铜1。You are"， gamesAwayb1（消息），"游戏远离青铜2"）TypeError： gamesAwayb1（）需要0个位置参数，但给出了1个

也许你可以创建一个简单的函数，

def gamesAwayb1(num):
    return 153 - int(num) # to convert string to num

并通过消息传递号码。内容当消息上的被触发时，类似于，gamesAwayb1（message.content）。

或者你不需要函数，如果你只需要，

async def on_message(message):
    if 0 < int(message.content) < 153:
        await message.channel.send("you are in Bronze 1.  You are {} games away from Bronze 2".format(153 - int(message.content)))

如果要检查输入中是否有有效数字，可以尝试以下操作：，

async def on_message(message):
    try:
        if 0 < int(message.content) < 153:
            await message.channel.send("you are in Bronze 1.  You are {} games away from Bronze 2".format(153 - int(message.content)))
    except ValueError:
        await message.channel.send("Please enter valid number")
