1)  pip install Django:  Django is a Python framework designed to make web development faster
  e.g.
  “Collecting Django
  Downloading Django-1.11.6-py2.py3-none-any.whl (6.9MB)
    100% |████████████████████████████████| 7.0MB 160kB/s
  Collecting pytz (from Django)
  Downloading pytz-2017.3-py2.py3-none-any.whl (511kB)
    100% |████████████████████████████████| 512kB 1.5MB/s
  Installing collected packages: pytz, Django
  Successfully installed Django-1.11.6 pytz-2017.3

	  Pytz allows accurate and cross platform timezone calculations using 	Python 2.4 or higher. It also solves the issue of ambiguous times at 	the end of daylight saving time.

2) pip list: Lists installed packages in case sensitive order
  e.g.
  Michaels-MacBook-Air-2:~ bamabrugge$ pip list
  DEPRECATION: The default format will switch to columns in the future. You can use --format=(legacy|columns) (or define a format=(legacy|columns) in your pip.conf under the [list] section) to disable this warning.
  click (6.7)
  Django (1.11.6)
  Flask (0.12.2)
  itsdangerous (0.24)
  Jinja2 (2.9.6)
  MarkupSafe (1.0)
  pip (9.0.1)
  pytz (2017.3)
  setuptools (36.6.0)
  Werkzeug (0.12.2)
  wheel (0.30.0)


3) pip install Django: tells me that I already have Django and pytz
  e.g.
  Requirement already satisfied: Django in /usr/local/lib/python2.7/site-packages
  Requirement already satisfied: pytz in /usr/local/lib/python2.7/site-packages (from Django)


4) pip freeze: while “pip list” lists installed packages, “pip freeze” outputs installed packages in requirements format.  “Requirement” files allow us to create an “environment:” a set of packages that work together.
  e.g.
  Michaels-MacBook-Air-2:~ bamabrugge$ pip freeze
  click==6.7
  Django==1.11.6
  Flask==0.12.2
  itsdangerous==0.24
  Jinja2==2.9.6
  MarkupSafe==1.0
  pytz==2017.3
  Werkzeug==0.12.2


5) pip uninstall Django:  there were a ton of files/packages that uninstalled…..too many to copy here :)
  e.g.
  Proceed (y/n)? y
  Successfully uninstalled Django-1.11.6

6) pip show Django: nothing returned after I uninstalled.
	After I reinstalled, I get basic information returned to me.
  e.g.
	Name: Django
  Version: 1.11.6
  Summary: A high-level Python Web framework that encourages rapid development and clean, pragmatic design.
  Home-page: https://www.djangoproject.com/
  Author: Django Software Foundation
  Author-email: [email protected]
  License: BSD
  Location: /usr/local/lib/python2.7/site-packages
  Requires: pytz


7) pip search Flask: search that generates all packages with the term “flask” in either the name or description of the package.
	e.g.
	Michaels-MacBook-Air-2:desktop bamabrugge$ pip search Flask
  Flask-User-05 (0.5)                            - Customizable User Account Management
                                                 for Flask: Register, Confirm email,
                                                 Login, Change username, Change
                                                 password, Forgot password and more.
  flask-restless-swagger-2 (0.0.3)               - Magically create swagger documentation
                                                 as you magically create your RESTful
                                                 API
