getting an error in discord.py v2.0 (cogs)

Question

I am trying to add cogs to my bot but It gives error(in repl.it):

this works without cogs

I also deleted the last discord.py(1.7.3)

and tried reinstalling the discord.py 2.0

this is on replit.com

that db and that secrets are replit specials also that doesnt effect the code in any ways

Answer 1

You also need to pass Self to the function

So instead of async def hello(ctx): use async def hello(self, ctx):
