SUPyF2 Objects/Classes-Exericse - 09. Movie (not included in final score)

Problem:
Create a class Movie. The __init__ method should receive a name and director.
It should also have default value of an attribute watched to be False.
There should also be a class attribute __watched_movies which will keep track of all the watched movies.
The class should have the following methods:
• change_name(new_name) - changes the name of the movie
• change_director(new_director) - changes the director of the movie
• watch() - change the watched attribute to True and increase the total watched movies class attribute
    (if the movie is not already watched)
• __repr__() - returns "Movie name: {name}; Movie director: {director}. Total watched movies: {__wached_movies}"

Examples:
    Test Code:
first_movie = Movie("Inception", "Christopher Nolan")
second_movie = Movie("The Matrix", "The Wachowskis")
third_movie = Movie("The Predator", "Shane Black")
first_movie.change_director("Me")
third_movie.change_name("My Movie")
first_movie.watch()
third_movie.watch()
first_movie.watch()
print(first_movie)
print(second_movie)
print(third_movie)

    Output:
Movie name: Inception; Movie director: Me. Total watched movies: 2
Movie name: The Matrix; Movie director: The Wachowskis. Total watched movies: 2
Movie name: My Movie; Movie director: Shane Black. Total watched movies: 2
