Answer 1

Do this:

list = {'2344','4324','3673','1325'}
@bot.event
async def on_message(message):
    if message.content in list:
        user = message.author
        role = discord.utils.get(ctx.guild.roles, name='testrole')
        await user.add_roles(role)
        embed = discord.Embed(title='Verification Successful', colour = discord.Colour.green())
embed.set_thumbnail(url='https://upload.wikimedia.org/wikipedia/commons/thumb/8/8c/White_check_mark_in_dark_green_rounded_square.svg/600px-White_check_mark_in_dark_green_rounded_square.svg.png')
        await message.channel.send(embed=embed)
        await message.channel.purge(limit=2)

@client.event async def on_message(message): message.content = message.content.lower() if message.content.startwith("command_name"): user = message.message.author role = discord.utils.get(message.guild.roles, name='testrole') await user.add_roles(role) embed = discord.Embed(title='Verification Successful', colour= discord.Colour.green()) await ctx.send(embed=embed, delete_after=1 )
