discord.py-rewrite Blacklist certain people from using the bot

问题

I am making a bot similar to "Discord Deliver" and "Discord Byte" where people can order virtual food, and I want to be able to black list certain people from using the bot. Is there any way of doing this? For all my commands i use @bot.command; I am specifying this as some people use on_message. Sorry that I don't have anything I've tried, I am relatively new to discord.py-rewrite.

回答1:

You can make a set containing their names and exit the function if the command's author's name is in that set.

blacklist = {'name1', 'name2', 'name3'}

@bot.command()
async def command(ctx):
    if ctx.author.name in blacklist:
        return

    # do rest of command

Using a set instead of a list for in is better because the lookup time is O(1) instead of O(n).
