python下载url图片并保存的小例程

啥也不说了，直接上代码

import numpy as np
import requests as req
from PIL import Image

import urllib.request



def process(string):  
    
  temp = str.split(string,',')
  this_url = temp[1]
  name = temp[0]
  while name[0] == '0':
      name = name[1:]
  print('Processing: ',name )
  resource =urllib.request.urlopen(this_url,timeout=10)  
  output = open('/raid/Guests/DaYea/another_image_dataset/img/'+name+'.jpg',"wb")  
  output.write(resource.read())  
  output.close()  
  
count = 0
f=open(r'/raid/Guests/DaYea/another_image_dataset/info/photos.txt')  

while True:
  count = count + 1
  line=f.readline()  
  if not line:break 
  if count >= 20000: #18896
    process(line)
f.close()
