4.4.2: Set theory methods.
The following program includes 10 cities that two people have visited. Write a program that creates:
1. A set all cities that contains all of the cities both people have visited.
2. A set same_cities that contains only cities found in both person1_cities and person2_cities.
3. A set different_cities that contains only cities found in only person1_cities or person2_cities.
Sample output for all cities:
['Accra', 'Anaheim', 'Bangkok', 'Bend', 'Boise', 'Buenos Aires', 'Cairo', 'Edmonton', 'Lima', 'London',
'Memphis', 'Orlando', 'Paris', 'Seoul', 'Tokyo', 'Vancouver', 'Zurich']
NOTE: Because sets are unordered, they are printed using the sorted () function here for comparison.

FaceUp card game In this assignment we will implement a made-up card game we'll call FaceUp. When the game starts, you deal five cards face down. Your goal is to achieve as high a score as possible. Your score only includes cards that are face up. Red cards (hearts and diamonds) award positive points, while black cards (clubs and spades) award negative points. Cards 2-10 have points worth their face value. Cards Jack, Queen, and King have value 10, and Ace is 11. The game is played by flipping over cards, either from face-down to face-up or from face-up to face-down. As you play, you are told your total score (ie, total of the face-up cards) and the total score of the cards that are face down. The challenge is that you only get up to a fixed number of flips and then the game is over. Here is an example of the output from playing the game: FACE-DOWN | FACE-DOWN | FACE-DOWN | FACE-DOWN | FACE-DOWN Face up total: 0 Face down total: -5 Number of flips left: 5 Pick a card to flip between 1…

In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…
In GO language. Create a struct that has student name, id, and GPA. Write functions to create a student, modify the student’s id, and modify the student's GPA, and print the student’s information. (This is like creating a class and methods). Now create an array of three students and test your functions. You may hardcode your values if using a web conpiler. (Please hardcode the values!)
