Not sure where to start

models.py 
from sqlalchemy import create_engine, Column, Integer, String
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import sessionmaker


engine = create_engine(‘sqlite:///movies.db’, echo=False)
Session = sessionmaker(bind=engine)
session = Session()
Base = declarative_base()


class Movie(Base):
    __tablename__ = ‘movies’

    id = Column(Integer, primary_key=True)

Challenge Task 1 of 1 The movie theater wants to know how many movies they have in their database with ‘The’ in the title. They want to post this fun fact on their social media. Create a new variable called the_movies that holds a query to find all products with ‘%The%’ in the movie_title and counts the number of returned values.\n*Hint:* Use filter() with .like()

I finally figured this out the_movies = session.query(Movie.movie_title).filter(Movie.movie_title.like("%The%")).count()

Start by making the variable and beginning the assignment. You know the value will involve calling the .query method on the session, and using .filter on the movie_title attribute of the Movie, making use of .like as mentioned in the hints.

You might want to review the Analyze Books video, particularly about half way through where a very similar query to find specific book titles is constructed.
