# Title: Assignment 05
# Description: Working with Dictionaries and Files
#              When the program starts, load each "row" of data
#              in "ToDoToDoList.txt" into a python Dictionary.
#              Add the each dictionary "row" to a python list "table"
# ChangeLog (Timothy McDowell, 5-17-22, Create a table of data):
# RRoot,1.1.2030,Created started script
# Timothy McDowell, 5-17-22 ,Added code to complete assignment 5

# -- Data -- #

# -- Processing -- #
# Step 1 - When the program starts, load the any data you have
# in a text file called ToDoList.txt into a python list of dictionaries rows (like Lab 5-2)
# TODO: Add Code Here
