写一个python爬虫爬取QQ音乐歌曲的代码

好的，以下是一个简单的Python爬虫爬取QQ音乐歌曲的代码：

import requests
import json

def get_song_list(keyword, page):
    """
    获取歌曲列表

if __name__ == '__main__':
    keyword = '周杰伦'
    page = 1
    song_list = get_song_list(keyword, page)
    for song in song_list:
        song_url = get_song_url(song['song_id'])
        print(song['song_name'], song['singer'], song['album'], song_url)

通过以上代码，我们可以获取到指定关键词下的歌曲列表，并且获取每首歌曲的播放链接。
