Discord.py hardcoded help command but it's better

hardhelp.py

@bot.command()
async def help(ctx: commands.Context, *, name: str = None):

    name = name.strip()

    if not name:

        commands = bot.commands

        embed = discord.Embed(title="Commands Menu", color=0x8DDFE3)

                name=cog.qualified_name,
                value=", ".join([i.name for i in cog.get_commands()]),
                inline=False,
            )

        misc = ", ".join([i.name for i in bot.commands if not i.cog])

        if len(misc) > 1:
            embed.add_field(name="Miscellanous", value=misc)

        await ctx.send(embed=embed)

            clog = bot.get_cog(raw_cog)

            embed = discord.Embed(color=0x8DDFE3)

Please Note

This example is just another one of those "doing things the way they are not intended to". It is not recommended to follow this way, prefer subclassing the default help command instead. You can refer this gist for that.

Here's a version of this command subclassed under commands.HelpCommand

which is ironically a better version than the original one since this version shows the subcommands of the asked group

(for the ones who aren't the type of ppl to "doing things the way they are not intended to")

bot.help_command = HelpCmd()

I didn't test this lmao
