如何遍历输入变量的数组，并读取输出变量b

Question

例如我有

commandz=[["yes","no"],["hi","hi"]]
async def handle_command(message):
    print('Noticed: ' + message.content)
    if message.content == 'tokenreset'+str(key):
        await client.send_message(message.channel, 'code accepted')
    i = 0
    for i in commandz[i][0]:
        comm = commandz[i][0]
        if comm == message.content:
            await client.send_message(message.channel, commandz[i][1])

我收到的错误信息是

C:\Users\trisimix>python "c:\Users\trisimix\compsocbot\main.py"
Found saved token in stored.py, use phrase tokenreset1424629785956179 to undo this.

Noticed: hi
Ignoring exception in on_message
Traceback (most recent call last):

    yield from getattr(self, event)(*args, **kwargs)
  File "c:\Users\trisimix\compsocbot\main.py", line 34, in on_message
    await handle_command(message)
  File "c:\Users\trisimix\compsocbot\main.py", line 42, in handle_command
    comm = commandz[i]
TypeError: tuple indices must be integers or slices, not str

我试图让我的程序使用if语句对照数组检查每个命令，然后用输出响应。你知道吗

从代码的第6行开始（即for循环）：

for comm in commandz:
    if comm[0] == message.content:
        await client.send_message(message.channel, comm[1])

您的代码的问题是，您正在循环一个字符串的字符（在commandz[0][0]），而您真正想要的是循环嵌套列表中的列表（即["yes","no"]和["hi","hi"]，这只是在commandz）。你知道吗

请注意，我使用变量comm作为commandz中的列表，而不是这些列表中的第一个索引，即yes和hi，我认为您打算将其用作
