Trying to create a discord bot - doesn't seem to connect to the bot

Question

I've been trying to develop my skills in Python and had a project to create a little web scraping bot for Discord.

My full code seems to work (prints what I want it to) but the discord element doesn't seem to connect to the bot.

The error I'm getting is:

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

The code I'm running (simply to put the bot online) is:

import discord
from discord.ext import commands

TOKEN = ''


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

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

client.run(TOKEN)

Of course the TOKEN is also filled in with the relevant key.

I'm using Python 3.7 on macOS Catalina and Atom code editor.
