#!/usr/bin/env python3

# python class file that allows  to read in a file split paragraphs then  print each line of
# paragraph and its characters  within that line  in chosen colour  to a terminal
# after each paragraph you  are then prompted  for input donated by $:  following which the next
# paragraph will be printed  as per above sequence
# Good practice for presentations  to explain points  whilst presenting media of some type  using a terminal
# This also aids as a prompt for to remind yourself of key issue  you need to discuss
