1.Principle

The main idea of this python program is to build a movie trailer website which can show posters of several movies and once clicked, show the trailer automatically.
fresh tomatoes

2. Details in realizing

We have 3 python files: entertainment_center.py, media.py, fresh_tomatoes.py.

media.py

This file defines a class Movie which provides a way to store movie related information

import webbrowser
class Movie():
 
    def __init__(self, movie_title, poster_image, trailer_youtube):
        # initialize instance of class Movie
        self.title = movie_title
        self.poster_image_url = poster_image
        self.trailer_youtube_url = trailer_youtube

    def show_trailer(self):
        # open a webbrowser and access in the page linked by url
        webbrowser.open(self.trailer_youtube_url)

entertainment_center.py

This file is the central program we need to run.** media.py** and fresh_tomatoes.py are imported.

import media
import fresh_tomatoes

In this file at first we build 6 instances of class Movie(), which contain what we need to post on the webpage. one example making an instance:

deadpool = media.Movie('Deadpool',
                       'http://www.sideshowtoy.com/wp-content/uploads/2016/01/marvel-deadpool-sixth-scale-hot-toys-feature-902628.jpg',  # noqa
                       'https://www.youtube.com/watch?v=tLmStxxzhkI')  # noqa

Then build a list to store the instances and execute the open_moives_page() function from fresh_tomatoes.py

movies = [deadpool, suicide_squad, doctor_strange,
          star_trek, assassin_creed, final_fantasy]
fresh_tomatoes.open_movies_page(movies)

fresh_tomatoes.py

This file contains the html codes. in the html codes {movie_tiles} {poster_image_url} {movie_title} remain to be replaced according to the instances established in entertainment_center.py. 2 functions are defined as well.

def create_movie_tiles_content(movies):
    # The HTML content for this section of the page
    content = ''
    for movie in movies:
        # Extract the youtube ID from the url
        youtube_id_match = re.search(r'(?<=v=)[^&#]+', movie.trailer_youtube_url)
        youtube_id_match = youtube_id_match or re.search(r'(?<=be/)[^&#]+', movie.trailer_youtube_url)
        trailer_youtube_id = youtube_id_match.group(0) if youtube_id_match else None

        # Append the tile for the movie with its content filled in
        content += movie_tile_content.format(
            movie_title=movie.title,
            poster_image_url=movie.poster_image_url,
            trailer_youtube_id=trailer_youtube_id
        )
    return content

This function will return reformed html codes which contain the movie contents.

def open_movies_page(movies):
  # Create or overwrite the output file
  output_file = open('fresh_tomatoes.html', 'w')

  # Replace the placeholder for the movie tiles with the actual dynamically generated content
  rendered_content = main_page_content.format(movie_tiles=create_movie_tiles_content(movies))

  # Output the file
  output_file.write(main_page_head + rendered_content)
  output_file.close()

  # open the output file in the browser
  url = os.path.abspath(output_file.name)
  webbrowser.open('file://' + url, new=2) # open in a new tab, if possible

This file will build a html file, write in the well formated html codes and open the webbrowser, show the page.
