Python Dictionary-Bot Questions

I was making a discode dictionary bot. The function I want is for the user to enter a word and the meaning of the word through a command to the bot. So what's been conceived!It's input (word) (meaning), but the problem is that the bot separates words and their meanings by spaces, so if the meaning gets longer, only the sentence before the space is saved as meaning. For example, if you type !input anarchism is a~~, When you print it out, it only outputs up to anarchism. I think it's because there's a space between the word anarchism and is. Please look at my code and answer me how to fix it.

import discord

from discord.ext import commands
from discord.utils import get

bot = commands.Bot(command_prefix='!',intents=discord.Intents.all())

front_command = "!"

user_input = ""

user_output = ""

check_number = 0



@bot.event

async def on_ready():

    print('Logging in..: ')

    print(bot.user.name)

    print('connection was succesful')

    await bot.change_presence(status=discord.Status.online, activity=discord.Game("Testing"))



@bot.command()

async def input(ctx, arg1, arg2):

    global check_number

    temp_f = open("user.txt","r")

    datafile = temp_f.readlines()

    if len(datafile) == 0:

        temp_f.close()

        temp_f = open("user.txt","w")

        temp_f.write(ctx.author.name + " " + str(arg1) + " " + str(arg2) +"\n")

        await ctx.send("Registration completed!")

    else:

        for i in range(len(datafile)):

                temp_f.write('\n'.join(datafile))

                await ctx.send("There is aleready "+str(arg1)+" related input, so it is changed to input now!")
