First Gist! A really basic ping cmd using discord.py

pingcmd.py

from discord.ext import commands


def letteremoji(letter):
    '''
    Converts a letter to a discord-syntax (uppercase) emoji
    
    Params:
    letter - the letter you want to convert to a emoji (only works with the latin alphabet)
    '''
    
    return f":regional_indicator_{letter.lower()}:"


class PingCommand(commands.Cog):

    def __init__(self, bot):
	    self.bot = bot

        
    # ↓↓↓ Main command here!!! ↓↓↓
    @commands.command(description='Checks my latency!')
    async def ping(self, ctx):
        
        await ctx.send(f'{letteremoji("p")} {letteremoji("o")} {letteremoji("n")} {letteremoji("g")} :ping_pong: \n> **{round(self.bot.latency * 1000)}ms**')
    
    
def setup(bot):
    bot.add_cog(PingCommand(bot))
