Python3中 from urllib import request 与 import urllib.request 区别

from urllib import request 与 import urllib.request 区别：

粘两段代码就懂了

from urllib import request

response = request.urlopen("http://www.baidu.com")
print ( response.read() )

import urllib.request

response = urllib.request.urlopen("http://www.baidu.com")
print ( response.read() )
