Discord.py Repeat message, delete command - discord.py

Question

I've gotten it to repeat the message in total, but how do I have it remove the command prefix, and delete the message?
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.content.startswith('.say'):
await message.channel.send(message.content)
client.run(os.getenv('TOKEN'))

Answer 1

To get rid of the bot sending the command prefix you can use [4:] when sending so the first four characters are not sent!
And to delete the message of the user you can use the command: await message.delete()
So the complete code would be:
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.content.startswith('.say'):
await message.channel.send(message.content[4:])
await message.delete()
client.run(os.getenv('TOKEN'))
I would check out the discord.py documentation linked here

I would recommend using discord.ext.commands here is your code made into a commands.Bot instead of discord.client
use .say LONGMESSAGE HERE to invoke the command
import discord
from discord.ext import commands
import os
bot = commands.Bot(command_prefix='.')
#bot.event
async def on_ready():
print('We have logged in as {0.user}'.format(client))
#bot.command()
async def say(ctx,* , data:str = None):
if not data:
return await ctx.send('please enter some data')
await ctx.message.delete()
await ctx.send(data)
bot.run(os.getenv('TOKEN'))
