Python学习笔记--创建类：电影网站

来源：互联网发布：厦门大学大数据实验室编辑：程序博客网时间：2024/06/01 08:23

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 webbrowserclass 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
