How to give one role to multiple discord user using the user id

I want to give one role named helper to multiple users whose user id’s are in a list called user_id

Here is my code:

@client.command()
async def role(ctx):
   user_id = ['752535843490616142' , '852495843390536197', '752595643220636947']
   role = discord.utils.get(ctx.message.guild.roles, name = "Helpers")   
   for member in user_id:
       await member.add_roles(role)
       await ctx.send('roles have been given')

This is the error I got:

Ignoring exception in command role:
Traceback (most recent call last):
  File "C:Usersupaayanaconda3libsite-packagesdiscordextcommandscore.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "D:Python projectsDiscord BotsMC Server botLocaluntitled0.py", line 22, in role
    await member.add_roles(role)
AttributeError: 'str' object has no attribute 'add_roles'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:Usersupaayanaconda3libsite-packagesdiscordextcommandsbot.py", line 939, in invoke
    await ctx.command.invoke(ctx)
  File "C:Usersupaayanaconda3libsite-packagesdiscordextcommandscore.py", line 863, in invoke
    await injected(*ctx.args, **ctx.kwargs)
  File "C:Usersupaayanaconda3libsite-packagesdiscordextcommandscore.py", line 94, in wrapped
    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: AttributeError: 'str' object has no attribute 'add_roles'

Answer

I started by renaming some of the variables for clarity. I then got the member object using the user_ids and then added the role. Finally, I moved the await ctx.send('roles have been given') outside of the for loop so that it’ll only send a single message.

@client.command()
async def role(ctx):
    user_ids = [752535843490616142, 852495843390536197, 752595643220636947]
    role = discord.utils.get(ctx.guild.roles, name="Helpers")
    for user_id in user_ids:
       member = ctx.guild.get_member(user_id)
       await member.add_roles(role)
    await ctx.send('roles have been given')
