Create a function named delete_challenge that takes a Challenge as an argument. Delete the specified Challenge. Your function shouldn't return anything

crud.py 
from models import Challenge


def create_challenge(name, language, steps=1):
    Challenge.create(name=name,
                     language=language,
                     steps=steps)


def search_challenges(name, language):
    return Challenge.select().where(
        Challenge.name.contains(name),
        Challenge.language==language
    )


def delete_challenge(Challenge):
  Challenge.delete()

We don't use .delete() to delete an instance of a model, but we use a method with a very similar name: .delete_instance().

When I ran the same code, I received the message: delete_instance() missing 1 required positional argument: 'self' I was able to pass in the correct argument and it passed after that!
