使用的到的知識點：

1. requests庫的 requests.get(url, headers=headers),headers是爬取僞裝頭，僞裝成瀏覽器爬取數據。
2. BeautifulSoup(web_data.text, 'lxml') 將爬取到的數據格式化，select()方法根據網頁上的Copy selector 提取元素。get_text()獲取元素中的文字信息。
3. split('-')將字符串以'-'號分開，split('-')[0]取第一個元素。
4. ['https://www.kugou.com/yy/rank/home/{}-31308.html?from=rank'.format(number)for number in range(1,6)] 生成一個url列表。
