How to count how many users are online, offline, in total on the server, and display them in embed from the bot?

Question

Python

I recently started learning a new programming language for me "Python", and started with bots.
I wanted to make information about the server, by type:

But how much I fiddle around I can’t do it, then errors, then the code is not correct.
Full code: here

@bot.command()

async def time( ctx, user: discord.Member ):
  youstatus = users[str(member.status)]
  all_online_server = ctx.guild.member_count
  emb = discord.Embed( title = 'Информация:', description = 'Beta 0.0.8' , colour = discord.Color.green(), url = 'https://coderoffline.pw' )
  emb.add_field( name = "На сервере:", value = ctx.guild.member_count , inline=True)
  emb.add_field( name = "Status", value = ctx.guild.member_status )
  emb.add_field( name = "Не в сети:", value = ctx.guild.member_count , inline=True)
  emb.set_footer( text = ctx.author.name, icon_url = ctx.author.avatar_url )
  #emb.set_image( url = 'https://coderoffline.pw/img/logo-white.png' )
  #emb.set_thumbnail( url = 'https://coderoffline.pw/img/logo-white.png' )

  now_date = datetime.datetime.now()
  #emb.add_field( name = 'Онлайн:', value = (all_online_server 'человека' )
  #emb.add_field( name = 'Time', value = 'Time: {}'.format( now_date ) )

  await ctx.send( embed = emb )

bot.run(settings['token']) # Обращаемся к словарю settings с ключом token, для получения токена

Mistake:

Traceback (most recent call last):
