How do i make my discord.py bot go through a text file and if a user says a word in that file it will delete that message + how to make uptime command

Question

I want my discord.py bot to go through a text file and if a user says a word in that file it will delete that message

    elif msg.content == '***':
    await msg.channel.send("Dont curse")
    await msg.delete()

that is my code but i want to replace *** with a text document

And also another question i have some issues with an uptime command

async def on_ready():
    print("Bot is running")
    activity = discord.Game(name="!test", type=3)
    await client.change_presence(status=discord.Status.idle, activity=activity)
    channel = client.get_channel(944665750453497886)
    myid = '<@516236429689618467>'
    await channel.send("I am online "+myid)
    #Uptime code starts
    global startdate
    startdate = datetime.now()

@client.command()
async def uptime(ctx):
    now = datetime.now()
    uptime = startdate - now
    uptime = uptime.strftime('%d/%h/%M')
    await ctx.send(f'Uptime: {uptime}')
