Discord.py - passing an argument role functions

问题

I wanted to create a command, like !iknow @user . A normal verification bot I think. Here's my code, I only pasted the important parts:

import discord
from discord.ext import commands

@client.command(pass_context=True)
async def iknow(ctx, arg):
    await ctx.send(arg)

    unknownrole = discord.utils.get(ctx.guild.roles, name = "Unknown")
    await client.remove_roles(arg, unknownrole)

    knownrole =   discord.utils.get(ctx.guild.roles, name = "Verified")
    await client.add_roles(arg, knownrole)

(The Unknown role is automatically passed when a user joins the server.)

The problem is: I get an error on line 6 (and I think I will get on line 9, too).

File "/home/archit/.local/lib/python3.7/site-packages/discord/ext/commands/core.py", line 83, in wrapped
ret = await coro(*args, **kwargs) File "mainbot.py", line 6, in iknow await client.remove_roles(arg, unknownrole) AttributeError: 'Bot' object has no attribute 'remove_roles'

I just started learning python, so please don't bully me!

You're looking for Member.remove_roles and Member.add_roles.

You can also specify that arg must be of type discord.Member, which will automatically resolve your mention into the proper Member object.

Side note, it's no longer needed to specify pass_context=True when creating commands. This is done automatically, and context is always the first variable in the command coroutine.

import discord
from discord.ext import commands

client = commands.Bot(command_prefix='!')


@client.command()
async def iknow(ctx, arg: discord.Member):
    await ctx.send(arg)

    unknownrole = discord.utils.get(ctx.guild.roles, name="Unknown")
    await arg.remove_roles(unknownrole)

    knownrole = discord.utils.get(ctx.guild.roles, name="Verified")
    await arg.add_roles(knownrole)

client.run('token')
