Finally, create a function named initialize. your initialize() function should connect to the database challenges..

I get the error "name 'challenges' is not defined". I'm not sure what I've done wrong. Can someone point it out for me? Thanks!

initialize.py
from peewee import *

db = SqliteDatabase("challenges.db")

class Challenge(Model):
    name = CharField(max_length=100)
    language = CharField(max_length=100)
    steps = IntegerField(default=1)

    class Meta:
      database = db

def initialize():
  challenges.connect()
  challenges.create_tables("Challenge", safe = True)

Your code is close. You created the database as db so use that in the initialize function instead of challenges. Also the argument to create_tables is a list of models and not text.

def initialize():
  db.connect()
  db.create_tables([Challenge], safe = True)
