Ouch.

Do you have any network interfaces?  'ifconfig -a' will list them.

Do you have Network Manager installed?  Running?

This looks like a broken PPA upgrade, from whichever PPA that provides
Python 3.3 for you.

I suggest you attempt to remove both conflicting packages with

  sudo apt-get remove idle-python3.3 libpython3.3-stdlib --fix-missing

followed by

  sudo dpkg --configure -a
  sudo apt-get install --fix-missing

You can install them back later.  Perhaps from a different PPA -- I
recommend https://launchpad.net/~fkrull/+archive/ubuntu/deadsnakes, it
shouldn't have this problem.

This problem with 3rd-party Python packages isn't something that's
likely to have broken your network connectivity.
