Is there a way to stop a discord.py bot from mentioning roles?

Question

I'm making a discord bot with discord.py, and I have a say command, but you can make the bot mention any role. I have already stopped it from mentioning @everyone and @here, but I can't figure out how to stop it from mentioning roles. Here's the code

async def say(ctx, *, message=None):
message = message or "You have to type a message"
message_components = message.split()
if "@everyone" in message_components or "@here" in message_components:
    await ctx.send("You can not ping everyone")
    return

await ctx.message.delete()
await ctx.send(message)

Is the issue resolved? If so, please mark any of the answers as accepted. @temp84323 — Jarvis, Dec 25 '20 at 13:13

You can use regexes. Assuming only uppercase/lowercase alphanumeric characters are allowed for a valid username/role:

import re
user_regex = r"@[a-zA-Z0-9]+"
message = "I'm tagging @you and @you2 in this message!"
match = re.findall(user_regex, message)
if match:
    await ctx.send("You can not ping everyone")
    return

Of-course, you can use a well-sophisticated regex for your username, if you desire. Or you can figure out the regex for role as per your requirements and try matching accordingly.

actually role mentions don't look like this `@role` (only `everyone` and `here`), but like this `<@&role_id>` — Łukasz Kwieciński, Dec 24 '20 at 10:00

You can use message.role_mentions

mentions = message.role_mentions

my_role = ctx.guild.get_role(some_id)

if my_role in mentions:
    await ctx.send("You can't mention that role")

If you have multiple roles

my_roles = [] # a list of `discord.Role` objects

mentions = message.role_mentions

if any(role in mentions for role in my_roles):
    await ctx.send("You can't mention that role")

Also a better way of checking if @everyone and @here is mentioned in the message content itself, you can use the message.mention_everyone attribute

if message.mention_everyone:
    await ctx.send("You can't mention everyone")
