这是源代码

1. import urllib.request as u
   
2. r=u.Request('http://plaeckitten.com/g/500/600')
   
3. p=u.urlopen(r)
   
4. c=p.read()
   
5. with open("cat.jpg",'wb') as f:
   
6.     f.write(c)

网址拼错了，http://plaeckitten.com/g/500/600，正确代码：

1. import urllib.request as u
   
2. 
   
3. r = u.Request('http://placekitten.com/g/500/600')
   
4. p = u.urlopen(r)
   
5. c = p.read()
   
6. with open("cat.jpg", 'wb') as f:
   
7.     f.write(c)
