How to make a user check for a role when calling a command in discord?

Question

Python

I'm making a discord bot in Python and I want to check the role of the User,
For example, if the User does not have the "Admin" role, then the bot will display the message "You are not allowed to use this command"
And if there is, then execute.

How can this be checked?

Answer 1

role = discord.utils.find(lambda r: r.name == 'Admin', ctx.message.server.roles)
        if role in user.roles:
            await bot.say("у вас есть роль")
        else:
            await bot.say("у вас нет роли")
