Instead of creating an empty dictionary, you can build a dictionary literal an example could look like
| if title == None or genre == None or rating == None: | |
| return None | |
| movie_info['title'] = title | |
| movie_info['genre'] = genre | |
| movie_info['rating'] = rating | |
| return movie_info | |
| if title and genre and rating: | |
| movie = { | |
| "title": title, | |
| "genre": genre, | |
| "rating": rating | |
| } | |
| return movie |
| pass | ||
| # create movie information | ||
| movie_info = {} | ||
| if title == None or genre == None or rating == None: |

Here you are supposed to check if this is truthy but this only checks for None. To check if it's truthy you could so something like if not title or not genre or not rating
| return user_data | ||

To avoid iterating and modifying data at the same time, in this case, you could create one for loop with an if conditional that removes the movie from the watchlist and adds the movie to watched in one loop. As soon as we make a change we want to stop iterating. Here is a suggestion:
def watch_movie(user_data, title):
for movie in user_data["watchlist"]:
if movie["title"] == title:
user_data["watchlist"].remove(movie)
user_data["watched"].append(movie)
break
return user_data
| # ----------------------------------------- | ||
| def get_watched_avg_rating(user_data): | ||
| combined_rating = 0 | ||
| if user_data["watched"] == []: |

you don't need to compare an empty list here. The pythonic way would be if not user_data["watched"]
| # calculate average of rating | ||
| for movie in user_data["watched"]: | ||
| combined_rating += movie["rating"] | ||
| average = (combined_rating/len(user_data["watched"])) |

I suggest moving this out of the loop so you are only doing the average once.
| # use mode function to find genre mode of mode list | ||
| for movie in user_data["watched"]: | ||
| mode_list.append(movie["genre"]) | ||
| return statistics.mode(mode_list) |

Good job looking up different methods to use. I would also push you to think of your own implementation and get familiar with explaining how this method works under the hood.
| # ----------------------------------------- | ||
| def get_unique_watched(user_data): | ||
| # make list of friends movies | ||
| friend_movies = [] |

This was a good approach, to make your code even more efficient you could make friend_movies equal to a set() instead of an empty list. Then on line 71 you would add it to the set instead of appending it to the list.
| user_movies.append(movie["title"]) | ||
| # if movie not in users movie list, add to friend unique movies | ||
| friend_unique_movies = {} | ||
| for friend in user_data["friends"]: |

As an experienced developer, it took a few times to read through this loop and understand what was happening. Adding a comment explaining how the code is actually working inside of this for loop will make it easier for others to understand.
| user_most_watched_genre = get_most_watched_genre(user_data) | ||
| friend_unique_movies = get_friends_unique_watched(user_data) |

great job using those helper functions!
| favorite_movies = [] | ||
| for movie in user_data["favorites"]: | ||
| favorite_movies.append(movie) | ||
| # iterate over favorite movies and check if has not been watched by friends | ||
| movie_from_favorites = [] | ||
| for movie in favorite_movies: | ||
| if movie in user_unique_movies: | ||
| movie_from_favorites.append(movie) |

| movie_from_favorites = [] | |
| for movie in favorite_movies: | |
| if movie in user_unique_movies: | |
| movie_from_favorites.append(movie) | |
| for movie in movies: | |
| if movie in user_data['favorites']: | |
| recs.append(movie) |

Overall great job on your first project Shannon! I added a few suggestions on how you can refactor some of your code to be more efficient. Take a look and let me know if you have any questions. |
