urllib has been split up in Python 3. The urllib.urlencode() function is now urllib.parse.urlencode(), and the urllib.urlopen() function is now urllib.request.urlopen()
so
| a | b | c |
|---|---|---|
| Python2 | urllib.urlencode() | urllib.urlopen() |
| Python3 | urllib.parse.urlencode() | urllib.request.urlopen() |
