python3.8，也安装了requests库，代码哪里出错了，为什么爬取失败

import requests

url = "https://m.ip138.com/ip.asp?ip="

try:

  r = requests.get(url+'202.204.80.112')
  r.raise_for_status()
  r.encoding = r.apparent_encoding
  print(r.text[-500:])

except:

  print("爬取失败")

我试了下，代码没有问题啊，

# -*- coding：utf-8 -*-
import requests

url = "https://m.ip138.com/ip.asp?ip="

try:
  r = requests.get(url+'202.204.80.112')
  r.raise_for_status()
  r.encoding = r.apparent_encoding
  print(r.text[-500:])
except:
  print("爬取失败")
