In this assignment you are asked to modify your program written for A5 to use a dictionary instead of a list to process user requests and store new entries and updates. As with A5, you start with the following list data structure consisting of the movies year, title, and category. At the start of the program the list is:

movies = [[1965, 'The Sound of Music', 'musical'], [1972, 'The Godfather', 'drama'], [1977, 'Annie Hall', 'comedy'], [1990, 'Dances with Wolves', 'western'], [1992, 'Unforgiven', 'western'],

[1994, 'Forrest Gump', 'comedy'], [1995, 'Braveheart', 'historical'],

[1997, 'Titanic', 'historical'], [1998, 'Shakespeare in Love', 'comedy'], [2000, 'Gladiator', 'action'],

[2002, 'Chicago', 'musical'], [2009, 'The Hurt Locker', 'action'], [2010, 'The Kings Speech', 'historical'], [2011, 'The Artist', 'comedy'], [2012, 'Argo', 'historical'], [2013, '12 Years a Slave', 'drama'], [2014, 'Birdman', 'comedy'], [2015, 'Spotlight', 'drama'], [2016, 'Moonlight', 'drama'], [2017, 'The Shape of Water', 'fantasy']]

As with A5, include the above list as a given copy it into your program source. For A6, however, at the start of the program you are to build a dictionary that consists of the year as the key and the title and category as elements of a list that are the keys corresponding value. Looking up the values for key 2000, for example, returns [Gladiator, action]. A6 should otherwise look to the user exactly as A5. Only the internal logic built around a dictionary should change.

To refresh your memory the following is a sample menu for A5 as presented to the user:

menu = """ 1 - display winning movie by year 2 - display movie and category by year 3 - add movie and category to list p - print movie list q - quit

Select one of the menu options above """

The programs logic should be:

Read the movie list and build the dictionary

Process the users menu picks as with A5 using the dictionary instead of the list

To do this assignment:

Add the logic to build the dictionary and print it to convince yourself the dictionary is correct.

Modify your A5 code to use the dictionary instead of the list. This gives you practice building and using the

dictionary data structure.

Use the Python interpreter mode if needed to be sure your statements will have the results you want

Make sure your program has no syntax errors (statements or symbols Python doesnt recognize).

When the program is completely written and the syntax errors removed, test the programs logic by running

it multiple times. Use the list of inputs and expected outputs you developed earlier as a testbed.

Consider writing the program in small steps. First write the code to display the menu, then add logic to

prompt for input, then validate the prompt, then the item and cost prompts. Finally, add the code to calculate the category item and cost totals and display them.
