The fix merged by #1176 cleans up the deprecation warning, but breaks for all python versions prior to 3.4. This change uses some simple try/except blocks to successively look for venv or virtualenv without version checking or conditional imports:

import platform as p
try:
 import venv
 ve="venv"
except Exception:
 try:
  import virtualenv
  ve="virtualenv"
 except Exception:
  ve=""
print(p.python_version()+" "+ve)
