1. import requests
   
2. 
   
3. import re
   
4. 
   
5. url='http://image.baidu.com/search/index?ct=201326592&cl=2&st=-1&lm=-1&nc=1&ie=utf-8&tn=baiduimage&ipn=r&rps=1&pv=&fm=rs1&word=%E7%8E%8B%E8%80%85%E8%8D%A3%E8%80%80%E5%A3%81%E7%BA%B8&oriquery=%E7%8E%8B%E8%80%85%E8%8D%A3%E8%80%80&ofr=%E7%8E%8B%E8%80%85%E8%8D%A3%E8%80%80&sensitive=0'
   
6. req=requests.get(url=url)
   
7. req=req.text
   
8. req1=re.findall('http://image.namedq.com/uploads///-.jpg',req)    #（‘http://image.namedq.com/uploads/20180910/17/1536571851-ThPjKneprB.jpg’）

复制代码

如果输入#号后面的可以打印出来网址，输入前面的打印出来的什么都没有

1. for i in req1:
   
2.     print(i)

复制代码

我想找到所有（‘http://image.namedq.com/uploads/20180910/17/1536571851-ThPjKneprB.jpg’）这种格式的网址要怎么操作

你这样会触发贪婪模式的
