(PYTHON)Write a set of functions that record and average user responses to the Oscar Nominated movies from 2018.

Assume that each record includes 10 items. The first item should be the user number (starting with 1), and the remaining 9 should be a opinion from 0 to 5 starts for each of 9 movies listed below. The fields should be as follows:

Opinions numbers have the following interpretation

Some example entries as a list of lists:

user number starting with 1

rating for The Shape of Water

rating for Darkest Hour

rating for Dunkirk

rating for Phantom Thread

rating for Three Billboards Outside Ebbing, Missouri

rating for Get Out

rating for The Post

rating for Call Me by Your Name

rating for Lady Bird

0 : I did not see the movie, 1: Terrible, 2: Bad, 3: Average, 4: Good, 5: Fantastic

user_ratings = [[1,0,0,4,0,5,0,0,2,0],[2,2,1,0,5,5,1,0,1,3],[3,5,0,2,2,4,3,3,0,1]]

For example, the first record is for user number 1. That person saw the movies: Dunkirk, Three Billboards Outside Ebbing, Missouri, and Call Me by Your Name, but did not see the other movies.

Write a function add_oscar_opinions that takes a filename ending in ".tsv" as an argument.

Use os.path.isfile to check if a file with that filename exists. If it does exist, then read in the contents of the file. Since the line is in .tsv format, you should split each line by tabs.

The first line should consist of labels (user_number, The Shape of Water, etc.)

Each subsequent line has 10 columns compatible with this problem -- the first position is the user number, the other positions are user ratings. Save this record as a list and keep a list of such records, e.g., like user_ratings above.

Also, for each movie, tally the number of users who saw the movie and the total of their ratings.

Embed a request for additional users in a while loop.

If there are no additional users, exit the while loop.

For each additional user, make an additional user number (1 greater than the highest user number previously found) and query the user regarding their views of each of the movies. Create a record of this information and store it. If the input file did not exist, then the first user to be entered by the system will be user number 1. For each movie that this user saw, add one to the number of users who saw the movie and add that user's rating to the total rating for that movie.

Next, for each movie, print the total number of users and the average rating for that movie (the total rating divided by the number of users who saw it).

Finally, write the records into a file as indicated by the input parameter. If this file previously existed, it will be overwritten. Otherwise, it will be newly created. It will include both info from users that were in the original file (if the file already existed) and info from users entered interactively.
