I recently install python 3 via homebrew on my Mac, I wanted to find out the version of python that I was running so I typed in the command "python3 -v", but it gave me the code below:

import _frozen_importlib # frozen import _imp # builtin import sys # builtin import '_warnings' # <class '_frozen_importlib.BuiltinImporter'> import '_thread' # <class '_frozen_importlib.BuiltinImporter'> import '_weakref' # <class '_frozen_importlib.BuiltinImporter'> import '_frozen_importlib_external' # <class '_frozen_importlib.FrozenImporter'> import '_io' # <class '_frozen_importlib.BuiltinImporter'> import 'marshal' # <class '_frozen_importlib.BuiltinImporter'> import 'posix' # <class '_frozen_importlib.BuiltinImporter'> import _thread # previously loaded ('_thread') import '_thread' # <class '_frozen_importlib.BuiltinImporter'> import _weakref # previously loaded ('_weakref') import '_weakref' # <class '_frozen_importlib.BuiltinImporter'>

installing zipimport hook

import 'zipimport' # <class '_frozen_importlib.BuiltinImporter'>

installed zipimport hook

/usr/local/Cellar/python3/3.6.0/Frameworks/Python.framework/Versions/3.6/lib/python3.6/encodings/pycache/init.cpython-36.pyc matches /usr/local/Cellar/python3/3.6.0/Frameworks/Python.framework/Versions/3.6/lib/python3.6/encodings/init.py

(NOTE: The above code is not the full code that was displayed, but just part of it.)

after the above happened I ran the command "exit()" which gave me the code below:

because I'm new to programming, am not quite sure what I've done.

I just want to make sure that I haven't altered some of my system files by accidentally installing and delete important file, and that everything is okay?

I thought because I used Homebrew it would be contained in its own environment, so it couldn't affect the python that came installed with my Mac?
