In this section, we are providing you with two data files movies.json and ratings.json in JSON data format. The first data file is movie information directly from IMDB, including rating for some movies but not all. The second file is ratings from Twitter. Be careful: Not all movies in movies.json have a rating in ratings.json, and not all movies in ratings.json has relevant info in movies.json. The data can be read in its entirety with the following five lines of code:

import json

if __name__ == "__main__":

movies = json.loads(open("movies.json").read())

ratings = json.loads(open("ratings.json").read())

Both files store data in a dictionary. The first dictionary has movie ids as keys and a second dictionary containing an attribute list for the movie as a value. For example: print (movies['3520029'])

(movie with id '3520029') produces the output:

{'genre': ['Sci-Fi', 'Action', 'Adventure'], 'movie_year': 2010, '

name': 'TRON: Legacy', 'rating': 6.8, 'numvotes': 254865}

In this homework, assume you are given these two files called movies.json and ratings.json. Read the data in from these files.

Ask the user for a year range: min year and max year, and two weights: w1 and w2.

Find all movies in movies made between min and max years (inclusive of both min and max years).

For each movie, compute the combined rating for the movie as follows: (w1* imdb_rating + w2 * average_twitter_rating)/(w1+w2) where the imdb_rating comes from movies and average_twitter_rating is the average rating from ratings.

If a movie is not rated in Twitter, or if the Twitter rating has fewer than 3 entries, skip the movie.

Now, repeatedly ask the user for a genre of movie and return the best and worst movies in that genre based on the years given and the rating you calculated.

Repeat until the user enters stop.

A sample output of your program is given below (the second lines for each movie has a tab at the start of the line, and the rating is given in {:.2f} format.):

The example of the output:

Min year => 2000

Max year => 2016

2016

Weight for IMDB => 0.7

Weight for Twitter => 0.3
