Python Flask REST API API Protection Password hashing

Please help me out with the correct code for this challenge

Almost done!

Now I need you to update the create_user method so that it sets the User instance's password using the User.hash_password method you just created.

import datetime

from argon2 import PasswordHasher
from itsdangerous import (TimedJSONWebSignatureSerializer as Serializer,
                          BadSignature, SignatureExpired)
from peewee import *

DATABASE = SqliteDatabase('courses.sqlite')
HASHER = PasswordHasher()

class User(Model):
    username = CharField(unique=True)
    email = CharField(unique=True)
    password = CharField()

    class Meta:
        database = DATABASE

    def create_user(cls, username, email, password, **kwargs):
        email = email.lower()
                (cls.email == email) | (cls.username**username)
        except cls.DoesNotExist:
            user = cls(username=username, email=email)
            user.password = cls.set_password(password)
            return user
            raise Exception("User with that email or username already exists.")

    def verify_auth_token(token):
        serializer = Serializer(config.SECRET_KEY)
            data = serializer.loads(token)
        except (SignatureExpired, BadSignature):
            return None
            user = User.get(User.id == data['id'])
            return user


    def hash_password(password):
        return HASHER.hash(password)

    def set_password(password): 
        return HASHER.hash(password)

    def verify_password(self, password):
        return HASHER.verify(self.password, password)

    def generate_auth_token(self, expires=3600):
        serializer = Serializer(config.SECRET_KEY, expires_in=expires)
        return serializer.dumps({'id': self.id})

class Course(Model):
    title = CharField()
    url = CharField(unique=True)
    created_at = DateTimeField(default=datetime.datetime.now)

    class Meta:
        database = DATABASE

class Review(Model):
    course = ForeignKeyField(Course, related_name='review_set')
    rating = IntegerField()
    comment = TextField(default='')
    created_at = DateTimeField(default=datetime.datetime.now)
    created_by = ForeignKeyField(User, related_name='review_set')

    class Meta:
        database = DATABASE

def initialize():
    DATABASE.create_tables([User, Course, Review], safe=True)
