Permissions with discord.py without using ctx

Question

So, I wanted to set up a purge command for discord.py, but everyone is able to use it. I obviously want it just for people who have the manage messages permission. I don't really understand ctx commands yet, so I'd like to avoid that for now, and the only answers I can find to this involve using ctx , and setting it up as @bot.command . What I have right now is:

    elif message.content.startswith ('jb!purge'):
        searchargs = message.content.split(" ")
        if(len(searchargs) > 1):
            if(len(searchargs) > 2):
                await message.channel.send("Too many numbers! Please try `jb!purge <number>`")
            elif(len(searchargs) == 2):
                if has_permissions(manage_messages = True):
                    try:
                        output = int(searchargs[1])
                        await message.channel.purge(limit=output)
                    except ValueError:
                        await message.channel.send("That's not a number, silly!")
                else:
                    await message.channel.send("Go get the perms first, then try again.")

You can use TextChannel.permissions_for using the TextChannel object you have from Message.channel . You can simply pass it the Member object from Message.author .
With the Permissions object, you can then simply check Permissions.manage_messages .

You should really look into using the commands extension though.
