Look more closely here:
2019-07-03 22:21:46,676 INFO sqlalchemy.engine.base.Engine SELECT *
FROM reviews WHERE movie = %(movie)s
2019-07-03 22:21:46,676 INFO sqlalchemy.engine.base.Engine {'movie':
"('The Lego Movie'"}
2019-07-03 22:21:47,375 DEBUG sqlalchemy.engine.base.Engine Col
('movie', 'rating', 'username', 'review')
2019-07-03 22:21:47,376 DEBUG sqlalchemy.engine.base.Engine Row
("('The Lego Movie'", Decimal('1'), 'sms', '
a very cool movie')
The value in the "movie" column is literally:
('The Lego Movie'
ie. "open parenthesis, single quote, The Lego Movie, single quote"
Whatever you're doing to insert data into the database is broken.
Things like this also raise red flags:
check_for_review = engine.execute(check_for_review_statement,
movie=movie_title).fetchall()
check_for_review_splitted = str(check_for_review).split(',')
You're getting a list of rows, converting them to a string, and then
splitting that string on commas. This will break badly in anything but
the simplest of cases.
