_ Crawling reptiles combat static single image

[Python web crawler and information extraction] .MOOC Beijing Institute of Technology this video. Taught me to crawl static single image, I use a Mac, so there's a change made in the form of an address file, the code is as follows:

import requests
import os
url = "https://pic.feizl.com/upload/allimg/170614/1JZ0G23-4.jpg"
root = "/Users/leo/Desktop/lianxi/"
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")

Show crawling successful, the lianxi new desktop folder, memory correct picture. Note that under Mac file format should be/Users/leo/Desktop/lianxi/
