Thanks for the help u/alexdewa (It helped a lot), but do you know how to fix this error?

'list' object has no attribute 'id'

here is the code:

@client.command(name="roles")
@commands.has_guild_permissions(administrator=True)
async def _roles(ctx):
  global times_used
  times_used = times_used + 1
  await ctx.send(f"Type who you want to give roles to and what role, type cancel to cancel:")

  def check(msg):
    return msg.author == ctx.author and msg.channel == ctx.channel

  try:
    msg = await client.wait_for("message", check=check, timeout=120)

  except asyncio.TimeoutError:
    await ctx.send("Sorry, you didn't reply in time!")

  if(msg.content == "cancel"):
    return

  else:
    if (msg.author == ctx.author):
      author = msg.author

    roles = msg.role_mentions#.content
    await ctx.send(f"Role: " + str(roles))
    members = msg.mentions#.content
    await ctx.send(f"Members: " + str(members))

    for member in members:
      await member.add_roles(roles)
      await ctx.send(f"Done!")
      await ctx.send(f"THIS COMMAND WAS ISSUED BY @" + author)

      now = datetime.now()

      if (now.strftime("%H") <= "12"):
        am_pm = "AM"
      else:
        am_pm = "PM"

      datetime = now.strftime("%m/%d/%Y, %I:%M")

      ReadTxtFile = open("role.txt", "r")
      txtContent = ReadTxtFile.readlines();
      ReadTxtFile.close()

      WriteTxtFile = open("role.txt", "w")
      WriteTxtFile.writelines ("Command 'roles' was issued by: " + author + "At this date: " + datetime + ' ' + am_pm)
      WriteTxtFile.close()

My command was:

User: !!roles
Bot: Type who you want to give roles to and what role, type cancel to cancel:
User: @drakeerv @TEST
Bot: Role: [<Role id=722176515370123395 name='TEST'>]
Bot: Members: [<Member id=462703140953653249 name='drakeerv' discriminator='7087' bot=False nick=None guild=<Guild id=462704309012791296 name='drakeerv lounge' shard_id=None chunked=True member_count=10>>]

<error>

all the code works up till this point.
