MVC实现电影院

好的，下面是使用MVC模式实现电影院的示例代码。MVC模式将应用程序分为三个部分：模型（Model）、视图（View）和控制器（Controller）。每个部分都有自己的职责，使得应用程序的开发、维护和扩展更加方便。下面是代码：

# Model
class Movie:
    def __init__(self, name, duration, rating, seats):
        self.name = name
        self.duration = duration
        self.rating = rating
        self.seats = [False] * seats

    def reserve_seat(self, seat_number):
        if seat_number < 0 or seat_number >= len(self.seats):
            return False
        if self.seats[seat_number]:
            return False
        self.seats[seat_number] = True
        return True

    def __str__(self):
        return f"{self.name} ({self.duration} min, {self.rating}/10)"


class Cinema:
    def __init__(self, name, seats):
        self.name = name
        self.seats = seats
        self.movies = []

    def add_movie(self, movie):
        self.movies.append(movie)

    def get_movies(self):
        return self.movies


# View
class CinemaView:
    def show_movies(self, movies):
        print("Movies:")
        for i, movie in enumerate(movies):
            print(f"{i+1}. {movie}")

    def show_reservation_result(self, movie_name, seat_number, success):
        if success:
            print(f"You have successfully reserved seat {seat_number} in {movie_name}. Enjoy the movie!")
        else:
            print(f"Sorry, seat {seat_number} in {movie_name} has already been taken.")


# Controller
class CinemaController:
    def __init__(self, cinema, view):
        self.cinema = cinema
        self.view = view

    def show_movies(self):
        movies = self.cinema.get_movies()
        self.view.show_movies(movies)

    def reserve_seat(self, movie_name, seat_number):
        for movie in self.cinema.get_movies():
            if movie.name == movie_name:
                success = movie.reserve_seat(seat_number)
                self.view.show_reservation_result(movie_name, seat_number, success)
                return
        print(f"Sorry, we couldn't find the movie {movie_name}.")


# 使用示例
cinema = Cinema("ABC Cinema", 100)
movie1 = Movie("The Godfather", 175, 9.2, 50)
movie2 = Movie("The Shawshank Redemption", 142, 9.3, 50)
cinema.add_movie(movie1)
cinema.add_movie(movie2)

view = CinemaView()
controller = CinemaController(cinema, view)

controller.show_movies()
controller.reserve_seat("The Godfather", 10)
controller.reserve_seat("The Godfather", 10)
controller.reserve_seat("The Godfather", 60)

这个代码实现了一个简单的电影院系统，使用了MVC模式，将应用程序分为了三个部分：模型、视图和控制器。模型部分负责定义电影和座位的相关数据和行为；视图部分负责显示电影列表和预定座位的结果；控制器部分负责响应用户的操作，调用模型和视图的相关方法，完成相应的业务逻辑。
