将参数保存到变量时出现问题

Question

我有一些代码基本上只是从命令中获取 arg 并在 if 语句中将其与一些文本进行比较。我不知道为什么，但是当它尝试将 arg 保存到变量时，我不断收到此错误：

Ignoring exception in command raceinfo:
Traceback (most recent call last):
  File "C:\Users\User\AppData\Local\Programs\Python\Python38\lib\site-packages\discord\ext\commands\core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "C:\Users\User\Desktop\DiscordMMO\Scripts\Character_Creator.py", line 66, in some_crazy_function_name
    raceInfo = ctx.arg
AttributeError: 'Context' object has no attribute 'arg'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\User\AppData\Local\Programs\Python\Python38\lib\site-packages\discord\ext\commands\bot.py", line 903, in invoke
    await ctx.command.invoke(ctx)
  File "C:\Users\User\AppData\Local\Programs\Python\Python38\lib\site-packages\discord\ext\commands\core.py", line 855, in invoke
    await injected(*ctx.args, **ctx.kwargs)
  File "C:\Users\User\AppData\Local\Programs\Python\Python38\lib\site-packages\discord\ext\commands\core.py", line 94, in wrapped
    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: AttributeError: 'Context' object has no attribute 'arg'

这是代码的sn-p：

@bot.command(name="raceinfo")
async def some_crazy_function_name(ctx, arg):
        raceInfo = ctx.arg
        if raceInfo == "Human" or "human":

ctx 中没有名为 arg 的元素。如果要将arg 存储在变量中：raceInfo，只需执行raceInfo = arg。或者，不要将arg 作为参数，而是这样写：

@bot.command(name="raceinfo")
async def some_crazy_function_name(ctx, raceInfo):
    if raceInfo == "Human" or raceInfo == "human":
        print(raceInfo)  # Add whatever code you would like
