Question

For Python 3.8!

Copy and paste the following bolded code into IDLE:

movies = [[1939, 'Gone with the Wind', 'drama'],
          [1943, 'Casablanca', 'drama'],
          [1965, 'The Sound of Music', 'musical'],
          [1969, 'Midnight Cowboy', 'drama'],
          [1972, 'The Godfather', 'drama'],
          [1973, 'The Sting', 'comedy'],
          [1977, 'Annie Hall', 'comedy'],
          [1982, 'Ghandi', 'historical'],
          [1986, 'Platoon', 'action'],
          [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'],
          [2001, 'A Beautiful Mind', 'hisotrical'],
          [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']]

Movie List Menu

2 - display movie and category by year
3 - add movie and category to list for an entered year
p - print all movies in the list
pc - print by category
q - quit

selection = ''
while selection != 'q':
    print(menu)
    selection = input("Please select one of the options found above: ")

    if selection == "1":
      
    elif selection == "2":

This will be your starting template. From here, do the following:

1) Change the provided "movies" list (found above) to a dictionary with the year as the key and the movie title & category as the corresponding values. The rest of the code should reference the dictionary, NOT the list.

2) When run, the program displays a simple menu of options for the user. Depending on the option selected, a movie title for a given year is displayed, the title and category are displayed, or only movies in a specified category are displayed.

The program reads the options and validates that the choice is on the menu. If not, the user is prompted to enter a valid one. When a year is entered for options 1 and 2 a check is made to ensure it’s within a valid range (1927to 2019) and whether that year’s movie information is already in the dictionary. If the year is out of range the user is prompted to re-enter. If it is in range and in the dictionary, the information is displayed.

For the ‘p’ option the program iterates through the dictionary and prints the movie information in a readable format. Printing the entire dictionary with one print command is not sufficient. For ‘pc’, prompt for a category and print every movie title in the dictionary with the specific category. Print ‘no matches’ if there are no movies in the entered category.

3) For option 3, the program searches the dictionary to see whether the movie is already there. If it isn’t, the user is prompted to enter a year, title, and category. There values are validated by your program as follows:

- year –must be an integer between 1927 and 2019, inclusive

- title –must of a string of size less than 40

- category –must be one of these values: (‘drama’, ‘western’, ‘historical’, ‘musical’, ‘comedy’, ‘action’, ‘fantasy’, ‘scifi’)

If the movie is already on the list, display the entry and prompt the user to ask if they want to replace it with new information. If yes, prompt for the new information and validate as above.

For options 1 and 2, if the requested year is not found in the list ask the user if they want to enter a year/title/category. If yes, prompt and validate as above.

Answer 1

thanks for the question, here are the complete implementation of all the choices.
