当循环崩溃机器人

Question

while condition:
            try:
                msg = await self.client.wait_for('message', check=check, timeout = 60)
            except asyncio.TimeoutError:
                condition = False
                break
            else:
                my_num = msg.content.split(' ')
                if len(my_num) > 2:
                    await ctx.send("Seems like you added too many arguments... Only use `category` `number`", delete_after=2)
                category = my_num[0]
                try:
                    index = int(my_num[1])
                except ValueError:
                     await ctx.send("The second argument needs to be an integer", delete_after=2)
                except IndexError:
                     await ctx.send("Provide two arguments: `category` `number`  (example: plants 3)")
                if category.lower() == "plants":
                    try:
                        my_query = new_list[index-1]
                    except IndexError:
                        await ctx.send("the number you wrote doesn't exist!", delete_after=2)
                    queried_potion = all_items[my_query]
                    try:
                        signs = queried_potion['sign']
                    except KeyError:
                        signs = []
                    try:
                        symbols = queried_potion['symbol']
                    except KeyError:
                        symbols = []
                    sign = " | ".join(signs) if len(signs) != 0 else "None"
                    symbol = " | ".join(symbols) if len(symbols) != 0 else "None"      
                    em = discord.Embed(title=f"Information for: {my_query}", description= f"**Symbols:** \n{symbol} \n\n**Signs:**\n {sign}", color = self.client.theme)
                    await mess.edit(embed=em)

上面是我为某人编写的代码，循环执行了我希望它执行的操作，但出现了一些错误。在“wait_for”超时后，由于某种原因，bot崩溃。我似乎找不到任何理由来解释原因

使用的所有变量都已定义，并且没有错误 机器人超时后就死了

知道为什么吗

根据wait_for documentation，提供超时时间（默认为无）将引发asyncio.TimeoutError

在代码中：

try:
   msg = await self.client.wait_for('message', check=check, timeout = 60)
except asyncio.TimeoutError:
   condition = False
   break

这会导致您中断while循环（请注意，将条件设置为false不会改变任何东西，因为您已经退出了循环）。看起来机器人并没有崩溃，更像是机器人完成了程序的执行

也许你想要的是不要设置timeout
