Python中使用requests库爬取网络图片

import requests
import os

url = "http://img0.dili360.com/ga/M02/32/FE/wKgBzFSORXuACp8AABXyQnlRi7U325.tub.jpg@!rw9"#图片地址
root = "D://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("文件保存成功")
    else:
        print("文件已存在")
except:
    print("爬取失败")
