how to read a line in discord

I am writing a bot for discord and there is a command ($ bone) in which the bot writes the following: "select a number from 1 - 9" and after that the user should answer and here's how I can read the line in which he wrote the number?

As alluded to in the comments, we will use a coroutine called wait_for, that waits for events like message: https://discordpy.readthedocs.io/en/latest/api.html#discord.Client.wait_for

Because these are the same events we might hook into with bot.event, we will be able to process the returned message.

@bot.command()
async def bone(ctx):
    await ctx.send("Select a number 1-9")
    
    def my_check_func(message): #A checking function: When we return True, consider our message "passed".
        if message.author == ctx.author: #Make sure we're only responding to the original invoker
            return True
        else:
            return False

    response = await bot.wait_for("message", check=my_check_func) #This waits for the first message event that passes the check function.
    #This execution process now freezes until a message that passes that check is sent,
    #but other bot interactions can still happen.
    c = response.content #equal to message.content, because response IS a message
    if c.isdigit() and 1 <= int(c) <= 9: #if our response is a number equal to 1, 9, or between those...
        await ctx.send("You sent: {}".format(response.content))
    else:
        await ctx.send("That's not a number between 1 and 9!")

Real example interaction to prove it works:

Cook1
$bone

Tutbot
Select a number 1-9
Cook1
4

Tutbot
You sent: 4

Cook1
$bone

Tutbot
Select a number 1-9

Cook1
no

Tutbot
That's not a number between 1 and 9!
