python No module named 'urlparse'
1、ModuleNotFoundError: No module named 'urllib2'
在python3.x版本中，urllib和urllib2包集合成在一個包了
import urllib2
response = urllib2.urlopen(request)
改為
import urllib.request
response = urllib.request.urlopen("http://www.fyunw.com")
2、ModuleNotFoundError: No module named 'urlparse'
3.0版本中已經將urllib2、urlparse、和robotparser併入了urllib中，並且修改urllib模組，其中包含5個子模組，即是help()中看到的那五個名字。

import urlparse
my_url = urlparse.urlparse(url)
改為

my_url = urllib.urlparse(url)
