python爬取音乐id时出错。

Question

utf-8
```import requests
from lxml import etree
import json
url = "http://music.163.com/playlist?id=2182968685"
headers = {'Host': 'music.163.com',
           'Referer': 'http://music.163.com/',
           'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8',
           'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64)AppleWebKit/537.36(KHTML, like Gecko)Chrome/79.10.3945.130 Safari/537.36'
           }
s = requests.session()
r = s.get(url, headers=headers)
results = etree.HTML(r.content)
print(results)
results = results.xpath('//span/a/@href')
#print(results)
for result in results:
    print(result)
上面是代码，结果如下：
<Element html at 0x2246160fac8>
/user/home?id=60348755
javascript:void(0)
javascript:void(0)
javascript:void(0)
javascript:void(0)
javascript:void(0)
/artist?id=${x.id}
/song?id=${x.id}
/song?id=${x.id}
/song?id=${x.id}
/song?id=${x.id}
/song?id=${x.id}
/song?id=${x.id}
/song?id=${x.id}
/song?id=${x.id}
/song?id=${x.id}
望各位大神指点迷津，到底是那里出了问题。

你的规则提取的范围太大了，可以把你的xpath规则改一下：results = results.xpath('//ul[@class="f-hide"]/li/a/@href')
