本文使用python制作一个简单的电影网页，上面显示电影名字和海报，点击海报时，会播放预告片（预告片引自YouTube，播放预告片网络需要可以连上YouTube)

1、media.py

import webbrowser
class Movie:
def __init__(self, movie_title, movie_storyline, poster_image, trailer_youtube):#构造函数
self.title = movie_title
self.storyline = movie_storyline
self.poster_image_url = poster_image
self.trailer_youtube_url = trailer_youtube

def show_trailer(self):
webbrowser.open(self.trailer_youtube_url)

2、fresh_tomatoes.py

import webbrowser
import os
import re
