Lowercase -v is not version, it's "verbose". and -vv is "very verbose".
So it's not crash, just a verbose message about importing.

> 2.Anaconda does not provide more information. Is that expected?

output of -V and -VV is implementation detail.  No standard format is specified 
by Python language.
PyPy has different output too.

[issue29806] Requesting version info with lowercase -v or -vv causes an import crash

2017-03-13 Thread Anne Moroney 

New submission from Anne Moroney:

In trying to test the new feature in 3.6.0, 
$ python -VV  # get more info than python -V or python --version 
I found several oddities. 

1.On both  Amazon Linux AMI Python 2.7.12 and also Anaconda Python 3.6.0, using 
lowercase v's causes a crash on some kind of import.

1a.AWS first lines are:
[ec2-user@ip-172-31-2-101 ~]$ python -v
# installing zipimport hook
import zipimport # builtin
# installed zipimport hook
# /usr/lib64/python2.7/site.pyc matches /usr/lib64/python2.7/site.py
import site # precompiled from /usr/lib64/python2.7/site.pyc

1b.Conda first lines are:
(py36aws)me:tool-aws me$ python -v
import _frozen_importlib # frozen
import _imp # builtin
import sys # builtin
import '_warnings' # 
//etc 

1c.In both cases, after lots of stuff, must quit python with 
quit()

2.Anaconda does not provide more information. Is that expected?
(py36aws) $ python -VV
Python 3.6.0 :: Continuum Analytics, Inc.
(py36aws)$ python -V
Python 3.6.0 :: Continuum Analytics, Inc.
(py36aws)$ python --version
Python 3.6.0 :: Continuum Analytics, Inc.
