🟢 GREEN! 🟢
Hey y'all!
Overall, this looks great! It passes all the tests and I didn't find any major mishaps, so you are receiving a green for the viewing party project!
Two things I would love for y'all to focus on/think about as you move forward with your programming journey!
-
The first is consistency! Sometimes y'all would pull out a specific list from the dictionary and other times y'all wouldn't! Either way works (with a slight preference for accessing the lists directly) as long as y'all are treating the lists the same way each time!
-
When you start to see yourself with a triply nested loop, see if you are able to pare it down. While triply nested loops can and do work, they can drastically slow down our program. In most cases, if we have that level of nesting, we are able to shrink it down to just one or two loops. If we aren't able to, it might be a sign to rethink our approach!
Great job, y'all!

These tests are a great start! Just a reminder that right now, y'all are only checking to see if the movie titles are the same. A more comprehensive test would actually just check to see if the movies themselves are the same. For example:
assert friends_unique_movies[0] == FANTASY_4
| recommendations = get_new_rec_by_genre(sonyas_data) | ||
|
|
||
| # Assert | ||
| assert len(recommendations) == 0 |
| pass | ||
| movie = {} | ||

This approach is great at making sure we have all our bases covered! One thing to remember, however, is that both None and an empty string are falsy conditions for strings. Therefore, the conditional
if title == None or title == "":
is actually the same conditional as
if not title:
This allows us to make both checks at once as opposed to having to separate them out!

Great use of the function you wrote before!

This is just a small thing, but a slightly more descriptive variable here might be better. Maybe instead of using "movies", you can use "recs" to signify that what you are outputting are recommendations rather than just random movies!

Remember that instead of checking each title in unique_watched_user_movies, we can compare specific movies to each other.
I love the way you created unique_watched_user_movies using the helper function from wave 4. But now that we have that particular list, what if we just looped through the user_data["favorites"] and checked to see if each movie was in unique_watched_user_movies. This won't necessarily save us on complexity(remember that in will technically count as a loop in most cases), but it will save us a nested loop!
In the grand scheme of things, when we have a nested structure like the one in this project, it's a good idea to check entire dictionaries against each rather than check dictionary key-value pairs against each other!
