Quote, PEP-8:
- Imports should usually be on separate lines, e.g.:
Yes: import os
import sys
No: import sys, os
it's okay to say this though:
from subprocess import Popen, PIPE
It explicitly states later its entirely OK to import classes. It never
says anything else directly, except in the example given, it shows you
importing a constant. So, its giving implicit approval to that without
really directly saying anything about it.

You're right, I missed that.
