如何让机器人通过 discord.py 中的命令离开公会？

Question

I want the bot leave a guild with a command . I tried this:

 @commands.command()
    @commands.check(user_is_me)
    async def leave(self,guild_id):
        await self.bot.get_guild(int(guild_id)).leave()

But this throws me the following error,

Ignoring exception in command leave:
Traceback (most recent call last):
  File "C:\Users\Rohit\AppData\Roaming\Python\Python37\site-packages\discord\ext\commands\core.py", line 83, in wrapped
    ret = await coro(*args, **kwargs)
  File "c:\Users\Rohit\Desktop\discord bots\quotient\cogs\owner.py", line 47, in leave
    await self.bot.get_guild(int(guild_id)).leave()
TypeError: int() argument must be a string, a bytes-like object or a number, not 'Context'

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

Traceback (most recent call last):
  File "C:\Users\Rohit\AppData\Roaming\Python\Python37\site-packages\discord\ext\commands\bot.py", line 892, in invoke
    await ctx.command.invoke(ctx)
  File "C:\Users\Rohit\AppData\Roaming\Python\Python37\site-packages\discord\ext\commands\core.py", line 797, in invoke
    await injected(*ctx.args, **ctx.kwargs)
  File "C:\Users\Rohit\AppData\Roaming\Python\Python37\site-packages\discord\ext\commands\core.py", line 92, in wrapped
    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: TypeError: int() argument must be a string, a bytes-like object or a number, not 'Context'

How do I solve it?

Answer 1

if you check documentation for command you see example like

@commands.command()
def test(ctx, arg)

When you use it in class then you have self as first argument but you still need other arguments

@commands.command()
def test(self, ctx, arg)

In you code it will be

def leave(self, ctx, guild_id)

But you use leave(self, guild_id) so you get context in variable guild_id and later you try to use this context in int() and in error message you get information about Context

int() argument must be a string, a bytes-like object or a number, not 'Context'
