Can I use if statement on list of values from SQLite?

I want to write a piece of code where I want to import the files from a SQLite database and then check if there is already a record that has some same attributes and in that case I want to not run the part of my if statement.

        for entry in entries:
            if beer.name not in entries[3]:
                print(f'New beer found: {beer.name}')
                print(f'Beer price: {beer.price}')
                beer.rating, beer.unt_id, beer.style = untappd_scraper(beer)
                if beer.unt_id is not entry[4]:
                    if site == "Hopt":
                        c.execute("INSERT INTO beers VALUES (:a, :b, :c, :g, :e, :f)", {'a': beer.name, 'b': beer.style, 'c': beer.rating,'g': beer.unt_id, 'e': beer.price, 'f': ''})
                        # conn.commit()
                    elif site == "Beerdome":
                        c.execute(
                            "INSERT INTO beers VALUES (:a, :b, :c, :g, :e, :f)", {'a': beer.name, 'b': beer.style, 'c': beer.rating, 'g': beer.unt_id, 'e': '', 'f': beer.price})
                        # conn.commit()
                conn.commit()

This does not seem to work, since the beer just keeps on being added, even tho its already multiple times in the list. So how can I change this code to make it work?
