Great work Sophia and Janice! You hit all the learning goals for this project and all tests are passing. You have earned a well-deserved 🟢 grade on this project ✨
I added comments, compliments, and hints on ways to refactor your code.
Keep up the great work! ✨

We can DRY up this code by returning the dictionary literal.
def create_movie(title, genre, rating):
# Check to see if there is a title, genre, rating
if not title or not genre or not rating:
return None
return {
"title": title,
"genre": genre,
"rating": rating

👍 Nice work!
We could also add some input validation (a function that confirms that the data passed into a function is valid (not falsy and the correct data type(s)) can make these functions more robust!
| def watch_movie(user_data, title): | ||
| # Check to see if movie's in watchlist, and put into watched | ||

👍 We can avoid unnecessary iterations by moving the return to the inside of the conditional. The moment that a matching movie is found we'll immediately exit the function. Imagine if the matching movie was found at the start of the list, we can exit the function right away instead of waiting until we've iterated through the entire length of the list.

👍 Nice work this is a really clean solution!

👍 Aren't helper functions super powerful!
We can also use list comprehension to build recommended_by_genre:
recommended_by_genre = [movie for movie in unique_movies if movie["genre"] == most_common_genre]| def get_rec_from_favorites(user_data): | ||
| friend_movies = [] | ||
| recommendations = [] | ||
|
|
||
| # Create list of friends movies | ||
| for watched_list in user_data["friends"]: | ||
| for movies in watched_list["watched"]: | ||
| friend_movies.append(movies) | ||
|
|
||
| # Recommend movies in user favorites but not in friends movies | ||
| for favorites in user_data["favorites"]: | ||
| if favorites not in friend_movies: | ||
| recommendations.append(favorites) | ||
|
|
||
| return recommendations |
| recommendations = get_new_rec_by_genre(sonyas_data) | ||
|
|
||
| raise Exception("Test needs to be completed.") | ||
| #Assert | ||
| assert len(recommendations) == 0 | ||
| # raise Exception("Test needs to be completed.") |
| # Assert | ||
| assert len(updated_data["watchlist"]) == 1 | ||
| assert len(updated_data["watched"]) == 2 | ||
| assert updated_data["watched"][1] == movie_to_watch |
| Pair Plan: | ||
| - Access needs | ||
| -Tuesday and Thursday cowoorking 1-3 | ||
| - after class if needed | ||
| - work from home if needed -starting 7pm ~ 2 hours | ||
|
|
||
| -your learning style | ||
| - hands on practice | ||
| -how you prefer to receive feedback | ||
| - through slack or in person | ||
| -team communication skill to improve on with this experience | ||
| - tell each other of changes we make on our own (like refactoring) | ||
