Getting Syntax Error On Python Discord Bot

import discord
import os

client = discord.Client()

@client.event
async def on_ready ():
  print ('We have logged in as{0.user}'.format(client))

@cient.event
async def on_message(message):
  if message.author == client.user:
    return

    if message.content.startswith('$hello'):
    await message.channel.send('Hello!')

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

Here is the code please tell where is the syntax error cause I am a beginner

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

@joelthcoder,
some typographical error was noticed in 7th line.

What IDE are you using? They usually provide more specific information on where issues are.
Looking at the code, indentation is flawed at several points - so that might already be the issue at hand.

Please look up basic Python syntax so you get a basic understanding on how commands work and where to use indentation.

yup added a space after on_ready and the parenthesis
