Discord bot in python issues

Question

I'm making a discord bot with Python following a video but my code won't execute, even though the one in video has no problem. I tried to loop it up, but everything I tried didn't help.

My code:

import discord
from discord.ext import commands


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


@client.event
async def on_ready():
    print('Hello server!')

client.run('MyToken')

Errors:

Traceback (most recent call last):

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

Answer 1

First of all, you should be careful because your token is visible in the error you gave us. Anyone with your token will have full control of your bot so be sure to regenerate it after you get this problem fixed.

Try doing: client = discord.Client()

Instead of: client = commands.Bot(command_prefix='!')

I ran it with that command and it worked
