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])

我收到的错误消息是

C:\Users\trisimix>python "c:\Users\trisimix\compsocbot\main.py"

    comm = commandz[i]
TypeError: tuple indices must be integers or slices, not str

我试图让我的程序使用if语句检查每个命令对数组，然后用输出进行响应。

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])

您的代码的问题在于您循环遍历字符串的字符（在commandz[0][0]中），而您实际想要的是循环遍历嵌套列表中的列表（即["yes","no"]和["hi","hi"]，只是commandz。

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，即我认为的yes和hi你打算用它作为
