Changes

:'''IPython''' is an interactive environment that allows us to run python code line by line as we write it. This will also act like a bash shell prompt allowing usres users to enter many a limited number of Bash shell commands. However, the commands that we will be running are lines of python code. You will notice this by seeing an [IN] prompt where to enter commands and an [OUT] prompt that will display output from issued commands. We will start creating scripts out of the code within this '''IPython''' environment.
