import urllib.requestresponse=urllib.request.urlopen('http://placekitten.com/g/500/600').read()
with open('mao.jpg','wb') as f:
f.write(response)
response.geturl()
print(response.info())
Traceback (most recent call last):

with open('mao.jpg','wb',encoding='utf-8') as f:
ValueError: binary mode doesn't take an encoding argument
为什么会报错啊1 with open('mao.jpg','wb') as f:试一试 把那个b 去掉
你代码直接 read() 获取网页源码了，返回 bytes 数据
你 geturl 只能对 urllib 获取的对象进行调用，但是却对 bytes 对象进行调用而导致报错
重新找个变量，赋值，对 urllib 对象进行调用函数即可，参考代码：
import urllib.request
response=urllib.request.urlopen('http://placekitten.com/g/500/600')
data = response.read()
with open('mao.jpg','wb') as f:
f.write(data)
response.geturl()
print(response.info())
