为什么命令要开火两次？

Question

我有一个机器人可以把你排到一个寻欢作乐的人那里。当队列数达到2时，它将重置为0。我有两个命令，一个用于第一个人，另一个用于第二个人记录他们的名字。但是，当我将其设置为2时，它将转到queue=0，并在queue=0时激发命令，使其激发两次。

我怎样才能解决这个问题？

  #If You Queue, And Role Requirement to Do So
  if message.content.startswith('-queue duos'): 
    global queue
    if queue == 1:
      role = discord.utils.get(message.guild.roles, id=830557149863608367)

      if role in message.author.roles:

        print('you have queued')
      
        global author2
        author2 = message.author
        print(author2)

        #Adds Role Duos
        role = discord.utils.get(message.guild.roles, id=830219965549510656) 
        await message.author.add_roles(role) 

        #Removes Role NoQueue
        role4 = discord.utils.get(message.guild.roles, id=830557149863608367)
        await message.author.remove_roles(role4)
      
        #Gives Message
        await message.channel.send('you have joined the duos queue sit tight!')

        
        queue += 1
        await message.channel.send(queue)

        if queue == 2:
          queue = 0

    #Is They Already Queued and Have Duos Role  
    else:

您正在更改队列变量，然后对其进行检查，这将导致该变量执行两次，解决此问题的简单方法是仅在队列的第一次检查中使用if，在其他检查中使用elif，即：

queue = 1
if queue == 1:
    #Do Something
    queue = 0
elif queue == 0:
    #Do Something else
    queue = 2
elif queue == 2:
    #Do Something else
    queue = 1

上面的示例代码只执行第一个if语句，因为elif仅在链接到的if语句未执行时才执行。
