python实现简单爬取图片保存到本地

import requests
import os
url="Http://lofter.nos.netease.com/soGou-Y1gxMDFIeFVHeWhCTkZaMEkzYWx1bGR5WEszQtdRTEZPcndxZWo3Q0dwTG1iZF9uVENpM0tCaUJNOXA1bmZkTA.jpg"
root="F://pics//";
path=root+url.split('/')[-1]
try:
  if not os.path.exists(root):
     os.mkdir(root)
  if not os.path.exists(path):
      r=requests.get(url)
      with open(path,'wb') as f:
            f.write(r.content)
            f.close()
            print("图片保存cg")
  else:
    print("保存失败")
except:
    print('爬取失败')
