Async def on_message(message): - Using repl.it

my code:

import discord
import os

client = discord.Client()

@client.event
async def on_ready():
  print('We have logged in as {0.user}'
  .format(client)
@client.event
async def on_message(message):
  if message.author == client.user:
    return

    if message.conetnt.startswith('A!Hello'):
      await message.channel.send('Hi Sussy!')

      client.run(os.getenv('TOKEN'))

Also this is for a discord bot. I got this from freecodecamp.org

what seems to be the problem?
