I typed python -v in my terminal and something weird happened
Question: Thinking I was about to check the version of Python installed on my computer,
I typed

    
    
    python -v 
    

in my terminal and I got a first line saying

> "installing zipimport hook", but then also a whole bunch of text (probably
> 50 or so lines of text), among which "import errno # builtin", "import posix
> # builtin", "import _codecs # builtin", and toward the end "Python 2.7.8
> |Anaconda 2.1.0 (x86_64)| (default, Aug 21 2014, 15:21:46)"

What did I do? And what did that command install?

**EDIT** : the `v` I typed in `python -v` was a lowercase `v`. When I now try
an uppercase `V`, I do get the version of Python on my computer.


Answer: You want `python -V` (uppercase) or `python --version`. The lowercase `-v`
means “verbose” and adds a bunch of diagnostic information to the output that
you can safely ignore.
