A kinda advanced custom "help" command for your Discord.py bots!

"""This custom help command is a perfect replacement for the default one on any Discord Bot written in Discord.py!
However, you must put "bot.remove_command('help')" in your bot, and the command must be in a cog for it to work.

You need to set three variables to make that cog run.

Hey, I just wanted to let you know that I've made a discord bot template on github, which offers some more utility funtions.
It's a solid base to begin with, also containing this help command :)

Have a look, if you're interested!

I ran into a couple of issues while using the help command, specifically getting the module because of the module[0] line, which should have just been module. I did a little reformatting and a little adding, and this is my finished code:

hey @rockwillck may you highlight the changes you made?
And could you also tell me the Exceptions that were raised?

Thank you ✌️

I added a join statement:

module = " ".join(module)

and then added:

if len(module) == 0:

but most importantly:
I got rid of

elif len(input) > 1:
emb = discord.Embed(title="That's too much.",
description="Please request only one module at once 😅",
color=discord.Color.orange())

because that was if the input was more than 1 character long, and that wasn't working.

And then I just added some more variables to make setup easier.

Just subclass the HelpCommand lol

The cmd is nice but it doesn't ignores the classes where no commands are in. For example the my profile save class. The cmd shows it up with typing the help cmd to discord but it's actually empty.
