In Py2x, have this code:

import urllib
s = urllib.urlopen('http://www.python.org')
print s

Run 2to3, on this, refactoring works only on import urllib and print
statements.

@@ -1,3 +1,3 @@
-import urllib
+import urllib.request, urllib.parse, urllib.error
 s = urllib.urlopen('http://www.python.org')
-print s
+print(s)

There urllib.urlopen, needs to be refactored into urllib.request.urlopen
