‘Member’ has no attribute ‘server’

In the given code below I was trying to give a role to the person who reacts to a message by using any emoji but this code throws me an error saying that 'Member' has no attribute 'server' what should I do now?

import discord
from discord.ext import commands
import random

client = discord.Client()





@client.event
async def on_ready():
 print('ready')

@client.event
async def on_reaction_add(reaction, user):
  channel = reaction.message.channel

  await channel.send(f'{user.name} has reacted by using    {reaction.emoji} emoji, his message was {reaction.message.content}')

  role = discord.utils.get(user.server.roles, name = 'Bot')

  await client.add_roles(user, role)

client.run('TOKEN') 

Answer

First off take a look at the documentation. It’ll tell you everything you need to know about what has what attributes. Also, server is called guild in discord.py. So use user.guild.roles instead.
