Improper token has been passed

[Helohacke]

Hey there , I need. A little help since I think I'm stuck in a loophole or something this is my code :

import discord
from discord.ext import commands
client = commands.Bot(command_prefix='>', self_bot=True)

@client.command()
async def ping(ctx):
await ctx.send('pong')

client.run("token")
Everytime I run this code , it says unauthorised improper token has been passed with httpexception: 401
I checked my account's token and it's valid but still it's saying the same
I have aiohttp: 3.7.4
Discord : 1.7.3
Discord.py : 1.7.3
Discord.py-self : 2.0.0
Discord-protos : 0.0.2

Can anyone suggest me changes I have checked there's nothing expect these packages no nextcord , selfcord , pycord etc .
