python - 如果有人离开 Discord.py，我的队列机器人正在清空队列

Question

我正在制作一个不和谐的机器人，它将 6 人排入队列，然后将 3 人随机分配到 2 个团队。然后这些团队进行私人 3v3。

我目前的问题是一旦一个人离开队列，它就会删除其他人，我不知道为什么通过查看我的代码。我有两个数组：

self.total 和 self.mention

self.total 用于存储用户 ID（以便我可以让机器人 DM 他们），而 self.mention 存储他们的标签（以便机器人可以标记它们）。self.qcount 用于统计排队的用户数，一旦达到 6 个用户就关闭队列。

下面是请假命令。

@commands.command()
    async def leave(self, ctx):
      if len(self.total) > 1:
       if ctx.author.mention in self.mention:
         self.total = self.total.remove(ctx.author)
         self.mention = self.mention.remove(ctx.author.mention)
         await ctx.send('You\'ve left the queue.')
         self.qcount -= 1
      elif len(self.total) == 1:
        if ctx.author.mention in self.mention:
          self.total = self.total.remove(ctx.author)
          self.mention = self.mention.remove(ctx.author.mention)
          await ctx.send('You\'ve left the queue.')
          self.total = []
          self.mention = []
          self.qcount = 0
      #elif len(self.total) > 1:    
        #if ctx.author.mention in self.mention:
          #self.total = self.total.remove(ctx.author)
          #self.mention = self.mention.remove(ctx.author.mention)
          #await ctx.send('You\'ve left the queue.')
      else: 
        await ctx.send('You\'re not in the queue.')
        return

下面是队列命令：

class queue(commands.Cog):
    def __init__(self, client):
        self.client = client
        self.qcount = 0
        self.total = []
        self.mention = []
         

    @commands.command()
    async def q(self, ctx):
        if self.qcount < 6:
           self.total
           self.mention
           guild = ctx.guild

           if ctx.author.mention in self.mention:
            await ctx.send('You\'re already queued.')
            return
           else: 
             #checking if the channel id matches the id allowed.
            if ctx.channel.id == 818292898067382297:
             self.qcount += 1
             await ctx.send('Added to the queue!' + ' ' + f'{ctx.author.mention}')
             #adds users to the queue
             self.total.append(ctx.author)
             self.mention.append(ctx.author.mention)
             if self.qcount == 6:

               #Takes the teams and shuffles, then splits into two teams.
               random.shuffle(self.total)
               blue = self.mention[:3]
               orange = self.mention [3:6] 
               blueDM = self.total[:3]
               orangeDM = self.total [3:6]
               #set p to equal a random user in the queue
               p = random.choice(self.total)

Answer 1

list.remove是一个始终返回的就地None操作。因此，当你做类似的事情时

self.total = self.total.remove(ctx.author)

self.total在你的离开命令中（你实际上在第 5、6、11和12 行中多次犯了同样的错误self.mention），你正在用None. 正在做

self.total.remove(ctx.author)

相反会产生预期的结果
